A Grafting Hydrogen-bonded Organic Framework for Benchmark Selectivity of C2H2/CO2 Separation under Ambient Conditions.

Reticular chemistry and pore engineering have garnered significant advancements in metal-organic frameworks and covalent organic frameworks, leveraging robust metal-coordination and covalent bonds. However, these achievements remain elusive in hydrogen-bonded organic frameworks, hindered by their inherent weakness in hydrogen bonding. Herein, we strategically manipulate the porosity of hydrogen-bonded frameworks through a grafting approach, culminating in the synthesis of two isomorphic HOFs, HOF-FJU-99 and HOF-FJU-100, with distinct pore environments. Remarkably, HOF-FJU-100, with its microporous architecture, not only showcases exceptional stability but also achieves unparalleled separation efficiency and ultrahigh selectivity for C2H2/CO2 mixtures (50/50, v/v) under ambient conditions. Its IAST selectivity value of 201 stands as a benchmark, towering over all previously reported HOFs. The pore of HOF-FJU-100 boasts an electrostatic potential highly favourable for C2H2 adsorption, as evidenced by single crystal X-ray diffraction analysis revealing multiple hydrogen bonding interactions between C2H2 molecules and the framework. In situ gas-carrier powder X-ray diffraction analysis underscores the adaptability of pore structure, dynamically adjusting its orientation in response to C2H2, thereby enabling a highly efficient and specific separation of C2H2/CO2 mixtures through specific adsorptive interactions.

Temporal trends, in-hospital outcomes, and risk factors of acute myocardial infarction among patients with epilepsy in the United States: a retrospective national database analysis from 2008 to 2017.

Background: The relationship between epilepsy and risk of acute myocardial infarction (AMI) is not fully understood. Evidence from the Stockholm Heart Study indicates that the risk of AMI is increased in people with epilepsy. This study aims to analyze the temporal trends in prevalence, adverse clinical outcomes, and risk factors of AMI in patients with epilepsy (PWE). Methods: Patients aged 18 years or older, diagnosed with epilepsy with or without AMI and hospitalized from January 1, 2008, to December 31, 2017, were identified from the National Inpatient Sample (NIS) database. The Cochran-Armitage trend test and logistic regressions were conducted using SAS 9.4. Odds ratios (ORs) were generated for multiple variables. Results: A total of 8,456,098 inpatients were eligible for our analysis, including 181,826 comorbid with AMI (2.15%). The prevalence of AMI diagnosis in PWE significantly increased from 1,911.7 per 100,000 hospitalizations in 2008 to 2,529.5 per 100,000 hospitalizations in 2017 (Ptrend < 0.001). Inpatient mortality was significantly higher in epilepsy patients with AMI compared to those without AMI (OR = 4.61, 95% CI: 4.54 to 4.69). Factors significantly associated with AMI in PWE included age (≥75 years old vs. 18 ~ 44 years old, OR = 3.54, 95% CI: 3.45 to 3.62), atherosclerosis (OR = 4.44, 95% CI: 4.40 to 4.49), conduction disorders (OR = 2.21, 95% CI: 2.17 to 2.26), cardiomyopathy (OR = 2.11, 95% CI: 2.08 to 2.15), coagulopathy (OR = 1.52, 95% CI: 1.49 to 1.54), dyslipidemia (OR = 1.26, 95% CI: 1.24 to 1.27), peptic ulcer disease (OR = 1.23, 95% CI: 1.13 to 1.33), chronic kidney disease (OR = 1.23, 95% CI: 1.22 to 1.25), smoking (OR = 1.20, 95% CI: 1.18 to 1.21), and weight loss (OR = 1.20, 95% CI: 1.18 to 1.22). Conclusion: The prevalence of AMI in PWE increased during the decade. Mortality rates were high among this population, highlighting the need for comprehensive attention to prophylaxis for risk factors and early diagnosis of AMI in PWE by physicians.

Prevalence and outcomes of atrial fibrillation in patients suffering prostate cancer: a national analysis in the United States.

Purpose: Although the adverse effects of atrial fibrillation (AF) on cancers have been well reported, the relationship between the AF and the adverse outcomes in prostate cancer (PC) remains inconclusive. This study aimed to explore the prevalence of AF and evaluate the relationship between AF and clinical outcomes in PC patients. Methods: Patients diagnosed with PC between 2008 and 2017 were identified from the National Inpatient Sample database. The trends in AF prevalence were compared among PC patients and their subgroups. Multivariable regression models were used to assess the associations between AF and in-hospital mortality, length of hospital stay, total cost, and other clinical outcomes. Results: 256,239 PC hospitalizations were identified; 41,356 (83.8%) had no AF and 214,883 (16.2%) had AF. AF prevalence increased from 14.0% in 2008 to 20.1% in 2017 (P < .001). In-hospital mortality in PC inpatients with AF increased from 5.1% in 2008 to 8.1% in 2017 (P < .001). AF was associated with adverse clinical outcomes, such as in-hospital mortality, congestive heart failure, pulmonary circulation disorders, renal failure, fluid and electrolyte disorders, cardiogenic shock, higher total cost, and longer length of hospital stay. Conclusions: The prevalence of AF among inpatients with PC increased from 2008 to 2017. AF was associated with poor prognosis and higher health resource utilization. Better management strategies for patients with comorbid PC and AF, particularly in older individuals, are required.

Hierarchical CoWO4/NixFeyS microspheres bearing crystalline-amorphous interface as a multifunctional platform for outperformed water splitting and sensitive hydrazine sensing.

Highly efficient and multifunctional electrocatalysts are of high value in energy transformation and electrochemical sensing. Herein, hierarchically architectured cobalt tungstate/nickel iron sulfide (CoWO4/NixFeyS) microspheres with a crystalline-amorphous interface have been prepared on bimetallic substrate of nickel-iron foam (NIF) by a two-step hydrothermal method. Electrochemical characterization shows that CoWO4/NixFeyS microspheres can boost the electrocatalytic activity effectively through the synergistic effect on the crystalline-amorphous interface. When the CoWO4/NixFeyS is applied as the electrocatalysts for oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER), the overpotentials at a high current density of 500 mA cm-2 are only 322.8 mV and 306.5 mV, respectively. The overall water splitting device composed of CoWO4/NixFeyS/NIF couple only needs a cell voltage of 1.80 V to reach a current density of 100 mA cm-2, and 2.19 V to reach 500 mA cm-2. The CoWO4/NixFeyS/NIF can be also utilized as an effective electrochemical platform for the sensing of toxic hydrazine in a wide range from 50 µM to 17.3 mM, with a detection limit of 46.4 µM. All these results display that the CoWO4/NixFeyS/NIF can be a high-performance multifunctional material for energy transformation and environmental pollutant monitoring.

Safety of selinexor as the only exportin 1 (XPO1) inhibitor so far: a post-marketing study based on the world Health Organization pharmacovigilance database (Vigibase).

BACKGROUND: Exportin 1 (XPO1) inhibitors are being developed as a new agent for anti-cancer therapies. This study aimed to broadly portray the adverse event (AE) profile of selinexor, an XPO1 inhibitor, in actual clinical practice. RESEARCH DESIGN AND METHODS: Disproportionality analyses were conducted by calculating the information component and reporting odds ratio in VigiBase over different reporting periods. All selinexor-related AEs were classified by system organ class (SOC) and preferred term (PT) according to the Medical Dictionary for Regulatory Activities. RESULTS: A total of 116,443 AEs were identified in 2,608 patients that received selinexor. Patients with cardiac disorders had a higher propensity for death. Thirteen SOCs and 125 PTs were identified as having a potential connection with selinexor. Notably, 29 suspected signals detected in our study were defined as significant AEs by the European Medicines Agency, including febrile neutropenia, pancytopenia, and acute kidney injury. Attention should be paid to these AEs, despite most toxicities being manageable and reversible. CONCLUSIONS: This study highlights a number of AEs associated with selinexor. Most toxicities are reversible but require careful management. The benefit of selinexor still outweighs the potential risks, indicating XPO1 inhibitors as promising agents.

In-hospital mortality and length of hospital stay in infants requiring tracheostomy with bronchopulmonary dysplasia.

PURPOSE: To investigate in-hospital mortality and hospital length of stay (LOS) in infants requiring tracheostomy with bronchopulmonary dysplasia (BPD). METHODS: We explored the correlation between tracheostomy with in-hospital mortality and LOS in infant patients hospitalized with BPD, using the data from Nationwide Inpatient Sample between 2008 and 2017 in the United States. In-hospital mortality and LOS was compared in patients who underwent tracheostomy with those patients who did not after propensity-score matching. RESULTS: A total of 10,262 children ≤2 years old hospitalized with BPD, 847 (8%) underwent tracheostomy, and 821 patients underwent tracheostomy were matched with 1602 patients without tracheostomy. Tracheostomy group was correlated with higher in-hospital mortality(OR(95%CI):2.98(2.25-3.95)) and prolonged LOS(absolute difference(95%CI):97.0(85.6-108.4)). CONCLUSIONS: Tracheostomy was correlated with increased in-hospital mortality and prolonged LOS. Such information may contribute to better decision-making process between clinicians and parents regarding tracheostomy to manage parent expectations, as well as better interdisciplinary teamwork.

Machine Learning Prediction Algorithm for In-Hospital Mortality following Body Contouring.

BACKGROUND: Body contouring is a common procedure, but it is worth attention because of concern for a variety of complications, and even the potential for death. As a result, the purpose of this study was to determine the key predictors following body contouring and create models for the risk of mortality using diverse machine learning (ML) models. METHODS: The National Inpatient Sample database from 2015 to 2017 was queried to identify patients undergoing body contouring. Candidate predictors, such as demographics, comorbidities, personal history, postoperative complications, and operative features, were included. The outcome was in-hospital mortality. Models were compared by area under the curve, accuracy, sensitivity, specificity, positive and negative predictive values, and decision curve analysis. RESULTS: Overall, 8214 patients undergoing body contouring were identified, among whom 141 (1.72%) died in the hospital. Variable importance plot demonstrated that sepsis was the variable with greatest importance across all ML algorithms, followed by Elixhauser Comorbidity Index, cardiac arrest, and so forth. The naive Bayes model had a higher predictive performance (area under the curve, 0.898; 95% CI, 0.884 to 0.911) among these eight ML models. Similarly, in the decision curve analysis, the naive Bayes model also demonstrated a higher net benefit (ie, the correct classification of in-hospital deaths considering a tradeoff between false-negatives and false-positives) compared with the other seven models across a range of threshold probability values. CONCLUSION: The ML models, as indicated by this study, can be used to predict in-hospital death for patients at risk who undergo body contouring.

Temporal trend and factors associated with post-endoscopic retrograde cholangiopancreatography pancreatitis in children in the USA: a nationwide, retrospective cohort study.

Pancreatitis is the most common adverse event following endoscopic retrograde cholangiopancreatography (ERCP). Meanwhile, the national temporal trend of post-ERCP pancreatitis (PEP) in children remains to be reported. The purpose of this study is to investigate the temporal trend and factors associated with PEP in children. We conducted a nationwide study using data from the National Inpatient Sample database during 2008-2017 and included all patients aged ≤ 18 years who underwent ERCP. The primary outcomes were temporal trends and factors associated with PEP. The secondary outcomes were in-hospital mortality, total charges (TC), and total length of stay (LOS). A total of 45,268 hospitalized pediatric patients who underwent ERCP were analyzed; of whom, 2043 (4.5%) were diagnosed with PEP. The prevalence of PEP decreased from 5.0% in 2008 to 4.6% in 2017 (P = 0.0002). In multivariable logistic analysis, adjusted risk factors of PEP were hospitals located in the West (aOR 2.09, 95% CI 1.36-3.20; P < .0001), bile duct stent insertion (aOR 1.49, 95% CI, 1.08-2.05; P = 0.0040), and end-stage renal disease (aOR 8.05, 95% CI 1.66-39.16; P = 0.0098). Adjusted protective factors of PEP were increasing age (aOR 0.95, 95% CI 0.92-0.98; P = 0.0014) and hospitals located in the South (aOR 0.53, 95% CI 0.30-0.94; P < .0001). In-hospital mortality, TC, and LOS were higher in patients with PEP than those without PEP. CONCLUSION: This study shows a decreasing national trend over time and identifies multiple protective and risk factors for pediatric PEP. Endoscopists can use the insights from this study to evaluate relevant factors before performing ERCP in children to prevent PEP and reduce the medical-care burden. WHAT IS KNOWN: • Although ERCP has become indispensable procedure in children as they are in adults, education and training programs for ERCP in children are underdeveloped in many countries. • PEP is the most common and most serious adverse event following ERCP. Research on PEP in adults showed rising hospital admission and mortality rates associated with PEP in the USA. WHAT IS NEW: • The national temporal trend of PEP among pediatric patients in the USA was decreasing from 2008 to 2017. • Older age was a protective factor for PEP in children, while end-stage renal disease and stent insertion into the bile duct were risk factors.

Data mining and analysis for emicizumab adverse event signals based on the Food and Drug Administration Adverse Event Reporting System database.

BACKGROUND: Emicizumab is the latest treatment for patients with hemophilia A. Its safety in real-world data is limited, and regulatory agencies and clinical researchers have raised concerns about the risk of adverse events. AIM: This study aimed to detect potential adverse event signals of emicizumab using the FDA Adverse Event Reporting System (FAERS) database. METHOD: Data in FAERS from the fourth quarter of 2017 to the second quarter of 2021 were searched. Cases of adverse events were extracted using the Preferred Term in the Medical Dictionary for Regulatory Activities (version 24.0). Disproportionality analysis was performed using the reporting odds ratio (ROR) and information component (IC) methods based on statistical shrinkage transformation. RESULTS: A total of 5,598,717 patients were included, of which 1,244 took emicizumab. A total of 703 emicizumab-related adverse event signals were mined, and 101 positive signals were detected. Haemarthrosis (ROR/ROR975/ROR025 = 155.62/184.34/131.38, IC/IC975/IC025 = 7.28/7.48/7.01), haemorrhage (ROR/ROR975/ROR025 = 71.01/81.18/62.12, IC/IC975/IC025 = 6.15/6.31/5.94), muscle haemorrhage (ROR/ROR975/ROR025 = 53.38/75.83/37.58, IC/IC975/IC025 = 5.74/6.16/5.15), traumatic haemorrhage (ROR/ROR975/ROR025 = 27.78/46.29/16.67, IC/IC975/IC025 = 4.80/5.40/3.92), haematoma (ROR/ROR975/ROR025 = 18.15/26.35/12.51, IC/IC975/IC025 = 4.18/4.63/3.55), device-related thrombosis (ROR/ROR975/ROR025 = 21.27/37.57/12.04, IC/IC975/IC025 = 4.41/5.08/3.43), and activated partial thromboplastin time prolonged (ROR/ROR975/ROR025 = 20.68/36.51/11.71, IC/IC975/IC025 = 4.37/5.04/3.39) had the strongest signal intensities. Haemorrhage, haemarthrosis, arthralgia, fall, and injection site pain were reported more frequently. CONCLUSION: This study found that mild arthralgia and injection site reaction were associated with emicizumab. Attention should also be paid to other serious adverse events related to emicizumab, such as acute myocardial infarction and sepsis, to ensure patient safety.

Cardiovascular Toxicities of Ibrutinib: A Pharmacovigilance Study Based on the United States Food and Drug Administration Adverse Event Reporting System Database.

Background: Although ibrutinib has been widely used to treat haematological malignancies, many studies have reported associated cardiovascular events. These studies were primarily animal experiments and clinical trials. For more rational clinical drug use, a study based on post-marketing data is necessary. Aim: Based on post-marketing data, we investigated the clinical features, time to onset, and outcomes of potential cardiovascular toxicities of ibrutinib. Methods: This disproportionality study utilised data from the 2014−2021 United States Food and Drug Administration Adverse Event Reporting System (FAERS) database. We used two disproportionality methods information component (IC) and reporting odds ratio (ROR)) to detect the potential cardiovascular toxicities of ibrutinib. Positive signals were defined as IC025 > 0 and ROR025 > 1. Results: A total of 10 cardiovascular events showed positive signals: supraventricular tachyarrhythmias, haemorrhagic central nervous system vascular conditions, ventricular tachyarrhythmias, cardiac failure, ischaemic central nervous system vascular conditions, cardiomyopathy, conduction defects, myocardial infarction, myocardial infarction disorders of sinus node function, and torsade de pointes/QT prolongation. Cardiomyopathy and supraventricular tachyarrhythmias were the two most common signals. Disorders of sinus node function were observed for the first time, which may be a new adverse effect of ibrutinib. Conclusions: This pharmacovigilance study systematically explored the adverse cardiovascular events of ibrutinib and provided new safety signals based on past safety information. Attention should be paid to some high-risk signals.

Temporal trends and outcomes in acute ischaemic stroke patients with a current or historical diagnosis of cancer.

BACKGROUND AND PURPOSE: The aim was to evaluate the temporal trends, characteristics and in-hospital outcomes of patients hospitalized with acute ischaemic stroke (AIS) between those with and without current or historical malignancies. METHODS: Adult hospitalizations with a primary diagnosis of AIS were identified from the National Inpatient Sample database 2007-2017. Logistic regression was used to compare the differences in the utilization of AIS interventions and in-hospital outcomes. For further analysis, subgroup analyses were performed stratified by cancer subtypes. RESULTS: There were 892,862 hospitalizations due to AIS, of which 108,357 (12.14%) had a concurrent diagnosis of current cancer (3.41%) or historical cancer (8.72%). After adjustment for confounders, patients with current malignancy were more likely to have worse clinical outcomes. The presence of historical cancers was not associated with an increase in poor clinical outcomes. Additionally, AIS patients with current malignancy were less likely to receive intravenous thrombolysis (adjusted odds ratio 0.66, 95% confidence interval 0.63-0.71). Amongst the subgroups of AIS patients treated with intravenous thrombolysis or mechanical thrombectomy, outcomes varied by cancer types. Notably, despite these acute stroke interventions, outcome remains poor in AIS patients with lung cancer. CONCLUSIONS: Although AIS patients with malignancy generally have worse in-hospital outcomes versus those without, there were considerable variations in these outcomes according to different cancer types and the use of AIS interventions. Finally, treatment of these AIS patients with a current or historical cancer diagnosis should be individualized.

Safety of sugammadex for reversal of neuromuscular block: A postmarketing study based on the World Health Organization pharmacovigilance database.

AIM: Residual neuromuscular blockade is a common complication after general anaesthesia. Sugammadex can reverse the action of aminosteroid neuromuscular blockers. This study aimed to explore sugammadex safety issues in the real world and determine the spectrum of adverse reactions. METHODS: All sugammadex-related adverse events reported in VigiBase between 2010 and 2019 were classified by group queries according to the Medical Dictionary for Regulatory Activities. A disproportionality analysis of data was performed using the information component (IC); positive IC values were deemed significant. RESULTS: Overall, 16 219 410 adverse events were reported and 2032 were associated with sugammadex. The frequent reactions were recurrence of neuromuscular blockade (n = 54, IC 6.74, IC025 6.33), laryngospasm (n = 53, IC 6.05, IC025 5.64), bronchospasm (n = 119, IC 5.63, IC025 5.36) and bradycardia (n = 169, IC 5.13, IC025 4.90). Fatal cases were more likely among patients with cardiac disorders, especially those over 65 years. In addition, the common adverse drug reactions (ADRs) differed between different age groups (P < .01). ADRs were higher in the 0-17 years age group than in other age groups. The onset time of common ADRs was typically within 1 day and 68.9% occurred within half an hour after sugammadex administration. CONCLUSIONS: Anaesthesiologists should carefully monitor the anaesthesia recovery period to correct the ADRs caused by sugammadex and recommend monitoring neuromuscular function throughout the anaesthesia process. Sugammadex should be used carefully in patients with cardiovascular diseases, and electrocardiography and hemodynamic changes should be monitored after medication.

Toxicity signals associated with secukinumab: A pharmacovigilance study based on the United States Food and Drug Administration Adverse Event Reporting System database.

AIMS: Secukinumab, the first interleukin 17A inhibitor, is widely used to treat immune diseases, including plaque psoriasis, psoriatic arthritis and ankylosing spondylitis. Recently, many studies have reported adverse events associated with secukinumab, including gastrointestinal disorders, infections and infestations, and hypersensitive and nervous system disorders. OBJECTIVE: Here, we aimed to explore the clinical characteristics, outcomes and time to onset of the four main toxicities of secukinumab using post-marketing data. METHODS: Our study utilized data from the United States Food and Drug Administration Adverse Event Reporting System (FAERS) database from 2015 to 2021, using disproportionality analysis. Toxicities were defined based on the standardized Medical Dictionary for Regulatory Activities queries. Two disproportionality methods were used to detect potential signals: information component (IC) and reporting odds ratio (ROR). The signals were defined as ROR025 > 1 and IC025 > 0. RESULTS: A total of 73 945 398 records were included in this study, of which 300 665 records were related to secukinumab. Diarrhoea (N = 3538), nasopharyngitis (N = 3458), pruritus (N = 4277) and rash (N = 3270) were the most common adverse events. Inflammatory bowel disease (IC025 /ROR025 = 3.25/9.69), genital candidiasis (IC025 /ROR025 = 3.46/11.54), dermatitis psoriasiform (IC025 /ROR025 = 1.94/4.04) and anosmia (IC025 /ROR025 = 1.62/3.17) had the highest IC025 values of all toxicities. The time to onset of the four toxicities was mainly concentrated in the first month. Some patients simultaneously presented with two or more toxicities. CONCLUSION: This pharmacovigilance study systematically explored the four main toxicities of secukinumab and provided new safety signals based on past safety information. Some high-risk signals need to be given attention.

Incidence and outcomes of acute high-risk chest pain diseases during pregnancy and puerperium.

Aim: To investigate the incidence and outcomes of acute high-risk chest pain diseases, including acute myocardial infarction (AMI), aortic dissection (AD), and pulmonary embolism (PE) during pregnancy and puerperium. Methods: The National Inpatient Sample was queried to identify pregnancy-related hospitalizations from January 1, 2008 to December 31, 2017. Temporal trends in the incidence and mortality of AMI, AD and PE were extracted. Results: Among 41,174,101 hospitalizations, acute high-risk chest pain diseases were diagnosed in 40,285 (0.098%). The incidence increased from 79.92/100,000 in 2008 to 114.79/100,000 in 2017 (Ptrend < 0.0001). The most frequent was PE (86.5%), followed by AMI (9.6%) and AD (3.3%). The incidence of PE in pregnancy decreased after 2014 and was lower than AMI and AD, while its incidence in puerperium was higher than AMI and AD consistently (Ptrend < 0.0001). Subgroup analysis showed the incidence of these diseases was higher in black women, lowest-income households, and elderly parturients (Ptrend < 0.0001). The mortality decreased from 2.24% in 2008 to 2.21% in 2017 (Ptrend = 0.0240), exhibiting 200-fold higher than patients without these diseases. The following factors were significantly associated with these diseases: aged ≥ 45 years (OR, 4.25; 95%CI, 3.80-4.75), valvular disease (OR, 10.20; 95%CI, 9.73-10.70), and metastatic cancer (OR, 9.75; 95%CI, 7.78-12.22). The trend of elderly parturients increased from 14.94% in 2008 to 17.81% in 2017 (Ptrend < 0.0001), while no such up-trend was found in valvular disease and metastatic cancer. Conclusion: The incidence of acute high-risk chest pain diseases, especially PE in puerperium, increased consistently. Although mortality has shown a downward trend, it is still at a high level. We should strengthen monitoring and management of acute high-risk pain diseases in pregnancy and puerperium, especially for black women, lowest-income households, and elderly parturients in the future.

Temporal trends, predictors of blood transfusion and in-hospital outcomes among patients with severe burn injury in the United States-A national database-based analysis.

BACKGROUND: Severe burn can be accompanied by life-threatening bleeding on some occasions, thus, blood transfusion is often required in these patients during their hospitalization. Therefore, we aimed to examine temporal trends, predictors, and in-hospital outcomes of blood transfusion in these patients in the United States. METHODS: The National Inpatient Sample was used to identify severe burn patients between January 2010 and September 2017 in the United States. Trends in the utilization of blood transfusion were analyzed using the Cochran-Armitage trend test. Moreover, propensity score matching (PSM) was employed, and then in-hospital outcomes were compared between these two groups in the matched cohort. Multivariable logistic regressions were further used to validate the results of PSM. RESULTS: Among 27,260 severe burn patients identified during the study period, 2120 patients (7.18%) received blood transfusion. Blood transfusion rates decreased significantly from 9.52% in 2010 to 5.02% in 2017 (p for trend <.001). In the propensity-matched cohort (2120 pairs with and without transfusion), patients transfused were at increased risk of in-hospital mortality (13.3% vs 8.77%, p < .001), overall postoperative complications (88.3% vs 72.59%, p < .001), longer hospital stays (defined as > median hospital stays = 5 d) (73.8% vs 50.6%, p < .001) and increased overall cost (defined as > median overall costs = 30,746) (81.6% vs 57.3%, p < .001). This was also the case for the multivariable analysis. CONCLUSIONS: Blood transfusion following severe burn injury may be associated with worse clinical outcomes. The utility for blood transfusion in burn patients warrants further prospective exploration.

Thromboembolic events in Janus kinase inhibitors: A pharmacovigilance study from 2012 to 2021 based on the Food and Drug Administration's Adverse Event Reporting System.

AIMS: As a new type of drug developed rapidly in recent years, Janus kinase inhibitors (JAKinibs) have caused controversy due to possible adverse reactions of thromboembolism. The aim of this study was to analyse and evaluate the association between thromboembolic events and the use of JAKinibs, on the base of the latest data in the Food and Drug Administration's Adverse Event Reporting System. METHODS: A disproportionality analysis was conducted, utilizing data from 1 January 2012 to 30 September 2021 in the FAERS. For each drug-adverse event pair, reporting odds ratio (ROR) and information components (IC) were calculated. RESULTS: A total of 15 positive safety signals were detected within the FAERS: ruxolitinib was significantly associated with portal vein thrombosis (ROR025 = 3.49, IC025 = 1.50); tofacitinib immediate release with pulmonary embolism (ROR025 = 2.09, IC025 = 1.02) and thrombosis (ROR025 = 1.15, IC025 = 0.18); tofacitinib extended release with pulmonary embolism (ROR025 = 1.27, IC025 = 0.26) and thrombosis (ROR025 = 1.29, IC025 = 0.33); baricitinib with deep vein thrombosis (ROR025 = 8.27, IC025 = 3.00), portal vein thrombosis (ROR025 = 1.97, IC025 = 0.63), pulmonary embolism (ROR025 = 7.90, IC025 = 2.94), thrombosis (ROR025 = 2.04, IC025 = 0.93) and venous thrombosis (ROR025 = 2.15, IC025 = 0.81); upadacitinib with pulmonary embolism (ROR025 = 1.25, IC025 = 0.25), pulmonary thrombosis (ROR025 = 5.32, IC025 = 2.33) and thrombosis (ROR025 = 2.72, IC025 = 1.39); and filgotinib with pulmonary embolism (ROR025 = 4.83, IC025 = 2.10). In the analysis of the time to onset of thromboembolic events, no obviously recognizable pattern was found. Several safety signals with embolic and thrombotic events (Standardised MedDRA Query) were found in the study. CONCLUSION: This pharmacovigilance study covered 8 types of JAKinib that are already on the market, and provided new safety signals based on past safety information. Some of these signals still need more medical evidence.

Drug-induced Stevens-Johnson syndrome: a disproportionality analysis from the pharmacovigilance database of the World Health Organization.

BACKGROUND: Stevens-Johnson syndrome is a rare but serious skin condition, which can lead to death. Stevens-Johnson syndrome is usually attributed to drug-induced reactions, thus making it vital for clinicians to prevent its occurrence by knowing the trigger drugs. The objective of this study was to comprehensively and systematically excavate the drugs that cause SJS to provide references for clinician. RESEARCH DESIGN AND METHODS: This is an observational, retrospective study, conducting a disproportionality analysis. Where the Information Component (IC) method and Reporting odds ratio (ROR) are used to mine the drugs that cause SJS. RESULTS: A total of 17,787,905 reports were extracted from VigiBase database, of which 25,051 reports were related to SJS. The 18-44 age group had the largest number of cases (N=7,973, 31.83%). A total of 295 drugs was detected as signals. Allopurinol (IC025/ROR025=5.86/69.84), phenytoin (IC025/ROR025=5.60/57.65) and carbamazepine (IC025/ROR025=5.25/43.88) were the top 3 strongest signals. Our study only considered the possibility of SJS caused by a single drug. CONCLUSIONS: Allopurinol, phenytoin and carbamazepine were three strongest signals. Garenoxaci, carbocisteine and dimetindene were strong signals, but there are no relevant cases reported on PubMed or specific SJS in labels, which need further study to verify.

Adverse events of alpelisib: A postmarketing study of the World Health Organization pharmacovigilance database.

AIMS: To explore and describe the adverse reaction signals in the safety reporting for alpelisib. METHODS: We performed a disproportionality analysis of the World Health Organization's VigiBase pharmacovigilance database from 1 January 2019 to 30 June 2021. Disproportionality analysis by information components (ICs) were used to evaluate the potential association between adverse events (AEs) and alpelisib. RESULTS: A total of 33 327 reports were extracted, 5695 of them were chosen with alpelisib as the suspected drug. After combining the same ID, 687 cases remained. The 45-64-years group had the most cases (n = 203, 29.55%). There were 129 Preferred Terms with significant signals. Hyperglycaemia (IC025 = 6.74), breast cancer metastatic (IC025 = 5.85) and metastases to liver (IC025 = 4.70) were the AEs with the strongest signal. AEs with the most cases were hyperglycaemia (n = 595), rash (n = 535) and diarrhoea (n = 475). CONCLUSION: We established a comprehensive list of AEs potentially associated with alpelisib. AEs with the most significant signals were hyperglycaemia, breast cancer metastatic, metastases to liver. The AEs with the most cases were hyperglycaemia, rash, diarrhoea, blood glucose increase and nausea.

Biosafety and efficacy evaluation of a biodegradable magnesium-based drug-eluting stent in porcine coronary artery.

Although the drug-eluting stent (DES) has become the standard for percutaneous coronary intervention (PCI)-based revascularization, concerns remain regarding the use of DES, mainly due to its permanent rigid constraint to vessels. A drug-eluting bioresorbable stent (BRS) was thus developed as an alternative to DES, which can be absorbed entirely after its therapeutic period. Magnesium (Mg)-based BRSs have attracted a great deal of attention due to their suitable mechanical properties, innovative chemical features, and well-proven biocompatibility. However, the primary disadvantage of Mg-based BRSs is the rapid degradation rate, resulting in the early loss of structural support long before the recovery of vascular function. Recently, a new type of patented Mg-Nd-Zn-Zr alloy (JDBM) was developed at Shanghai Jiao Tong University to reduce the degradation rate compared to commercial Mg alloys. In the present investigation, a poly(D,L-lactic acid)-coated and rapamycin eluting (PDLLA/RAPA) JDBM BRS was prepared, and its biosafety and efficacy for coronary artery stenosis were evaluated via in vitro and in vivo experiments. The degree of smooth muscle cell adhesion to the PDLLA/RAPA coated alloy and the rapamycin pharmacokinetics of JDBM BRS were first assessed in vitro. JDBM BRS and commercial DES FIREHAWK were then implanted in the coronary arteries of a porcine model. Neointimal hyperplasia was evaluated at 30, 90, and 180 days, and re-endothelialization was evaluated at 30 days. Furthermore, Micro-CT and optical coherence tomography (OCT) analyses were performed 180 days after stent implantation to evaluate the technical feasibility, biocompatibility, and degradation characteristics of JDBM BRS in vivo. The results show the ability of a PDLLA/RAPA coated JDBM to inhibit smooth muscle cell adhesion and moderate the drug release rate of JDBM BRS in vitro. In vivo, low local and systemic risks of JDBM BRS were demonstrated in the porcine model, with preserved mechanical integrity after 6 months of implantation. We also showed that this novel BRS was associated with a similar efficacy profile compared with standard DES and high anti-restenosis performance. These findings may confer long term advantages for using this BRS over a traditional DES.
