The SMILE study: Study of long-term methotrexate and iguratimod combination therapy in early rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation and joint destruction. Iguratimod (IGU) is a novel conventional synthetic disease-modifying antirheumatic drugs (csDMARD) with good efficacy and safety for the treatment of active RA in China and Japan. However, the long-term effects of IGU on the progression of bone destruction or radiographic progression in patients with active RA remain unknown. We aimed to investigate the efficacy and safety of iguratimod (IGU), a combination of methotrexate (MTX) and IGU, and IGU in patients with active rheumatoid arthritis (RA) who were naïve to MTX. This multicenter, double-blind, randomized, non-inferiority clinical trial was conducted at 28 centers for over 52weeks in China. In total, 911 patients were randomized (1:1:1) to receive MTX monotherapy (10-15mg weekly, n=293), IGU monotherapy (25mg twice daily, n=297), or IGU+MTX (10-15mg weekly for MTX and 25mg twice daily for IGU, n=305) for 52weeks. The patients' clinical characteristics, Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI), disease activity score in 28 joints-C-reactive protein (DAS28-CRP) level, and erythrocyte sedimentation rate (DAS28-ESR) were assessed at baseline. The primary endpoints were the proportion of patients with≥20% improvement according to the American College of Rheumatology (ACR20) response and changes in the van der Heijde-modified total Sharp score (vdH-mTSS) at week 52. The proportions of patients achieving an ACR20 response at week 52 were 77.44%, 77.05 %, and 65.87% for IGU monotherapy, IGU + MTX, and MTX monotherapy, respectively. The non-inferiority of IGU monotherapy to MTX monotherapy was established with the ACR20 (11.57%; 95% confidence interval [CI], 4.35-18.79%; P<0.001) and vdH-mTSS (-0.37; 95% CI, -1.22-0.47; P=0.022). IGU monotherapy was also superior to MTX monotherapy in terms of ACR20 (P=0.002) but not the vdH-mTSS. The superiority of IGU+MTX over MTX monotherapy was confirmed in terms of the ACR20 (11.18%; 95% CI, 3.99-18.37%; P=0.003), but not in the vdH-mTSS (-0.68; 95% CI, -1.46-0.11; P=0.091). However, the difference in the incidence rates of adverse events was not statistically significant. IGU monotherapy/IGU+MTX showed a more favorable clinical response than did MTX monotherapy. IGU may have some clinical benefits over MTX in terms of radiographic progression, implying that IGU may be considered as an initial therapeutic option for patients with active RA. https://classic.clinicaltrials.gov/, NCT01548001.

Safety Profile of a Cognitively Unimpaired Older Population with Elevated Cerebral Amyloid in a 4.5-Year Clinical Trial

BackgroundPreclinical Alzheimer’s disease is increasingly studied in clinical trials. Although safety signals are routinely monitored in clinical trial populations with Alzheimer’s disease, it can be challenging to identify new safety signals against background rates of age-related medical comorbidities.ObjectivesTo report detailed safety data from a cognitively unimpaired older population with evidence of elevated cerebral amyloid levels on amyloid positron emission tomography in the placebo arm of a Phase 3 clinical trial.DesignPhase 3, 4.5-year, multicenter, placebo-controlled trial.SettingPlacebo data from the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease (A4) study.ParticipantsEnrolled participants were aged 65–85 years with a global Clinical Dementia Rating score of 0, a Mini-Mental State Examination score of 2–-30, a Wechsler Memory Scale Logical Memory IIa (delayed recall) score of 6–18, and elevated brain amyloid levels on 18F-florbetapir positron emission tomography.MeasurementsStudy participants who received placebo were followed up with post-baseline safety measures. Assessments included review of concomitant medication and adverse events, the Columbia Suicide Severity Rating Scale, electrocardiograms, and neuroimaging (brain magnetic resonance imaging).ResultsIn total, 591 study participants (mean age [standard deviation] 71.9 [5.0] years) were assigned to and received placebo in the A4 study, and were followed up to 240 weeks. Participants were primarily White (93.9%) and from the United States (86.8%); 60.4% were women. The most common serious adverse events (incidence rate per 100 person-years) were pneumonia (incidence rate=0.4; 95% confidence interval=0.2–0.7) and atrial fibrillation (incidence rate=0.4; 95% confidence interval=0.2–0.7). The most common treatment-emergent adverse events were upper respiratory tract infection (incidence rate=10.9; 95% confidence interval=9.4–12.5), fall (incidence rate=7.7; 95% confidence interval=6.6–9.0), and nasopharyngitis (incidence rate=5.8; 95% confidence interval=4.8–6.9). The most common ischemia-related findings on magnetic resonance imaging were subcortical infarction (incidence rate=1.4; 95% confidence interval=1.0–2.0) and acute ischemia (incidence rate=0.6; 95% confidence interval=0.3–1.0). Emergent amyloid-related imaging abnormalities with hemosiderin deposition occurred in 32.8% of participants who received placebo; the primary factor associated with these events during the post-baseline period was the number of microhemorrhages at baseline (odds ratio=349.9; 95% confidence interval=247.6–494.4; adjusted p<0.001).ConclusionSafety findings in the placebo-treated group from the A4 study provide a robust characterization of expected safety in a clinical trial population with preclinical Alzheimer’s disease. These results may provide context in planning future studies and safety evaluations during ongoing blinded studies in preclinical Alzheimer’s disease.

Changes in the treatment landscape of metastatic hormone-sensitive prostate cancer following approval of upfront androgen receptor signaling inhibitors: A multicenter study.

A multicenter database was utilized to examine the current treatment landscape and clinical outcomes among patients with metastatic hormone-sensitive prostate cancer (mHSPC) following approval of upfront androgen receptor signaling inhibitors (ARSIs). We retrospectively analyzed patients with mHSPC who commenced treatment between February 2018 and June 2023. The Kaplan-Meier method was used to assess oncological outcomes, including time to castration-resistant prostate cancer (CRPC), progression-free survival 2 (PFS2, duration from initial treatment to tumor progression during second-line treatment), cancer-specific survival (CSS), and overall survival (OS). Cox regression analyses were performed to determine the impact of treatment choices on oncological outcomes. In addition, the incidence rate of adverse events was assessed. In total, 829 patients were analyzed; 42.5% received ARSIs with androgen deprivation therapy (ADT), 44.0% received combined androgen blockade (CAB), and 13.5% received ADT alone. Kaplan-Meier curves and multivariate Cox regression analyses indicated higher rates of CRPC and shorter PFS2 in patients treated with CAB versus ARSIs with ADT. By contrast, CSS and OS were not significantly different between the ARSI with ADT group and the CAB group. Grades 3-4 adverse events occurred in 1.9% of patients receiving CAB and 6.0% of those receiving ARSIs with ADT. Initial treatment with ARSIs in combination with ADT resulted in a longer time to CRPC and longer PFS2 compared to CAB. Although CAB and ADT alone were associated with fewer adverse events, ARSIs with ADT should be considered a first-line treatment option given its superior oncological outcomes.

Evaluating the Safety of the Intragastric Balloon: Spanish Multicenter Experience in 20,680 Cases and with 12 Different Balloon Models.

Intragastric balloon (IGB) is a minimally invasive and reversible option for obesity treatment. There is a worldwide growing number of different IGB models. The efficacy and safety profile for each model must be demonstrated. We aim to evaluate IGB safety profile according to the experience of the Spanish Bariatric Endoscopy Group (GETTEMO). A survey of 37 IGBs safety-related questions was sent to all GETTEMO members, to retrospectively collect a multicenter Spanish registry. Incidence, causes, and resolution of both major and minor complications and adverse events (AEs), including legal consequences, differentiated for each balloon model were evaluated. Secondary outcome was weight loss data to confirm efficacy. Twenty-one Spanish hospitals experienced in IGBs responded. The overall data encompassed 20,680 IGBs, including 12 different models. Mean %TBWL of 17.66 ± 2.5% was observed. Early removal rate due to intolerance was 3.62%. Mean major complications rate was 0.70% (> 1% in Spatz2, HB, and Spatz3 models), mainly complicated gastric ulcer. Minor AEs rate was 6.37%, mainly esophagitis. Nine cases (0.04%) required surgery. A single case of mortality (0.0048%) occurred. Seven lawsuits (0.0034%) were received, all with favorable resolution. In the Spanish experience accumulating 20,680 IGBs and including 12 different balloon models, a low incidence rate of major complications and minor AEs are observed (0.70% and 6.37%, respectively), mostly resolved with medical/endoscopic management. IGB shows good tolerance and efficacy profile. These safety data are within the accepted quality standards.

Safety and efficacy of biliary suprapapillary metal and plastic stents in malignant biliary obstruction: a systematic review and meta-analysis.

Biliary drainage is vital in managing malignant biliary obstruction (MBO). Suprapapillary stenting has emerged as a viable alternative to transpapillary stenting and is performed using inside plastic (iPS) or metal stents (iMS). This meta-analysis aims to evaluate the outcomes of suprapapillary stent placement for MBO. The Embase, PubMed, and Web of Science databases were systematically searched to include all studies published before September 31, 2023, that reported on the outcomes of suprapapillary stents placed for MBO. Using the random-effect model, the pooled, weight-adjusted event rate estimate for the clinical outcomes was calculated with 95% confidence intervals (CIs). Twenty-eight studies were included, with a total of 1401 patients. The pooled clinical success rate was 98.9%. A subgroup analysis yielded non-significant differences between the iPS and iMS groups (99.3% vs. 98.6%, respectively; P = 0.44). The pooled incidence rate of adverse events (AE) with suprapapillary stents was 9.5%. In a subgroup analysis, the incidence of AEs with iPS was 10.7% compared to 9% in the iMS group without a statistical difference (P = 0.32). The most common adverse event was cholangitis (2.2%), followed by pancreatitis (1.1%), cholecystitis (0.5%), and bleeding (0.12%). When technically feasible, suprapapillary stenting for MBO is a viable endoscopic option with a high clinical success rate and acceptable adverse event rates. Both iPS and iMS exhibit similar efficacy.

Dual add-on therapy of gemigliptin and dapagliflozin in patients with type 2 diabetes inadequately controlled with metformin alone: The SOLUTION 2 study.

To evaluate the efficacy and safety of gemigliptin and dapagliflozin dual add-on therapy (GEMI + DAPA) to metformin in type 2 diabetes (T2D) patients who had inadequate glycaemic control on metformin alone, compared with a single add-on of either gemigliptin (GEMI) or dapagliflozin (DAPA) to metformin. In this randomized, double-blind, double-dummy, active-controlled, parallel-group, phase 3 study, 469 T2D patients treated with a stable dose of metformin for 8 weeks or longer were randomized to receive GEMI + DAPA (n = 157) and either GEMI (n = 156) or DAPA (n = 156). The primary endpoint was change in HbA1c levels from baseline at week 24. Baseline characteristics including body mass index and T2D duration were similar among groups. At week 24, the least square mean changes in HbA1c from baseline were -1.34% with GEMI + DAPA, -0.90% with GEMI (difference between GEMI + DAPA vs. GEMI -0.44% [95% confidence interval {CI}: -0.58% to -0.31%], P < .01) and -0.78% with DAPA (difference between GEMI + DAPA vs. DAPA -0.56% [95% CI: -0.69% to -0.42%], P < .01). Both upper CIs were less than 0, demonstrating the superiority of GEMI + DAPA for lowering HbA1c. The rates of responders achieving HbA1c less than 7% and less than 6.5% were greater with GEMI + DAPA (84.9%, 56.6%) than with GEMI (55.3%, 32.2%) and DAPA (49.3%, 15.3%). The incidence rate of adverse events was similar across groups, with low incidence rates of hypoglycaemia, urinary tract infection and genital infection. These results suggest that the addition of GEMI + DAPA to metformin as triple combination therapy was effective, safe and well-tolerated, especially for T2D patients who experienced poor glycaemic control on metformin alone.

Efficacy, Safety, and Pharmacoeconomic Evaluation of Injectable Spearhead Pit Viper Hemagglutinin in Local Hemostatic Treatment of Non-Ruptured Upper Gastrointestinal Bleeding

Objective: To evaluate the efficacy, safety, and drug affordability of injectable spearhead pit viper hemagglutinin (TTP) in the local hemostatic treatment of non-ruptured upper gastrointestinal bleeding, and to provide an evidence-based reference for its rational clinical application. Methods: 80 cases of acute non-variceal upper gastrointestinal bleeding patients admitted to the hospital from October 2022 to April 2023 were screened as research subjects, and divided into a control group and a research group, both including 40 patients. The control group was selected to give hemostatic treatment for endoscopic bleeding foci according to the condition in endoscopic operation by clamping and coagulation, while the research group was selected to provide local hemostatic treatment for non-ruptured bleeding foci in endoscopic operation. The study group was given hemostatic treatment to endoscopic bleeding foci during endoscopic operation according to the condition (endoscopic spraying hemostasis or submucosal injection hemostasis). The study observed and analyzed the effectiveness, adverse reactions, as well as hospital stay, and cost of the patients in the two groups. Results: The total effective rate of hemostasis in the control group was 75.00%, and the total effective rate of hemostasis in the study group was 95.00%, which was significantly better than that in the control group (P &lt; 0.05). The incidence rate of adverse events in patients in the experimental group was 5.00%, while that in the control group was 7.50%, and the difference between the two groups was not statistically significant (P &gt; 0.05). The hospital stay in the patients in the study group was 3.02 ± 1.41 days, and the average hospitalization cost was 5274.89 ± 1691.21 yuan, both of which were significantly lower than 5.93 ± 1.43 days, and 11220.12 ± 3202.14 yuan in the control group, and the difference was statistically significant (P &lt; 0.05). Conclusion: TTP, as a new type of hemostatic agent, can significantly improve the efficacy of upper gastrointestinal bleeding and has good affordability, so it can be considered for promotion and application in the clinic.

Risk of emergency hospital admission related to adverse events after antibiotic treatment in adults with a common infection: impact of COVID-19 and derivation and validation of risk prediction models

BackgroundWith the global challenge of antimicrobial resistance intensified during the COVID-19 pandemic, evaluating adverse events (AEs) post-antibiotic treatment for common infections is crucial. This study aims to examines the changes in incidence rates of AEs during the COVID-19 pandemic and predict AE risk following antibiotic prescriptions for common infections, considering their previous antibiotic exposure and other long-term clinical conditions.MethodsWith the approval of NHS England, we used OpenSAFELY platform and analysed electronic health records from patients aged 18–110, prescribed antibiotics for urinary tract infection (UTI), lower respiratory tract infections (LRTI), upper respiratory tract infections (URTI), sinusitis, otitis externa, and otitis media between January 2019 and June 2023. We evaluated the temporal trends in the incidence rate of AEs for each infection, analysing monthly changes over time. The survival probability of emergency AE hospitalisation was estimated in each COVID-19 period (period 1: 1 January 2019 to 25 March 2020, period 2: 26 March 2020 to 8 March 2021, period 3: 9 March 2021 to 30 June 2023) using the Kaplan–Meier approach. Prognostic models, using Cox proportional hazards regression, were developed and validated to predict AE risk within 30 days post-prescription using the records in Period 1.ResultsOut of 9.4 million patients who received antibiotics, 0.6% of UTI, 0.3% of URTI, and 0.5% of LRTI patients experienced AEs. UTI and LRTI patients demonstrated a higher risk of AEs, with a noted increase in AE incidence during the COVID-19 pandemic. Higher comorbidity and recent antibiotic use emerged as significant AE predictors. The developed models exhibited good calibration and discrimination, especially for UTIs and LRTIs, with a C-statistic above 0.70.ConclusionsThe study reveals a variable incidence of AEs post-antibiotic treatment for common infections, with UTI and LRTI patients facing higher risks. AE risks varied between infections and COVID-19 periods. These findings underscore the necessity for cautious antibiotic prescribing and call for further exploration into the intricate dynamics between antibiotic use, AEs, and the pandemic.

Is Endoscopic Ultrasound-Guided Hepaticogastrostomy Safe and Effective after Failed Endoscopic Retrograde Cholangiopancreatography?-A Systematic Review and Meta-Analysis.

Background/Objectives: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) has emerged as an alternative option for biliary drainage in cases of failed endoscopic retrograde cholangiopancreatography (ERCP). Limited data exist on the safety and efficacy of EUS-HGS. In this comprehensive meta-analysis, we aim to study the safety and efficacy of EUS-HGS in cases of failed conventional ERCP. Methods: Embase, PubMed, and Web of Science databases were searched to include all studies that evaluated the efficacy and safety of EUS-HGS. Using the random effect model, the pooled weight-adjusted event rate estimate for clinical outcomes in each group were calculated with 95% confidence intervals (CIs). The primary outcomes were technical and clinical success rates. Secondary outcomes included overall adverse events (AEs), rates of recurrent biliary obstruction (RBO), and rates or re-intervention. Results: Our analysis included 70 studies, with a total of 3527 patients. The pooled technical and clinical success rates for EUS-HGS were 98.1% ([95% CI, 97.5-98.7]; I2 = 40%) and 98.1% ([95% CI, 97.5-98.7]; I2 = 40%), respectively. The pooled incidence rate of AEs with EUS-HGS was 14.9% (95% CI, 12.7-17.1), with bile leakage being the most common (2.4% [95% CI, 1.7-3.2]). The pooled incidence of RBO was 15.8% [95% CI, 12.2-19.4], with a high success rate for re-intervention (97.5% [95% CI, 94.7-100]). Conclusions: Our analysis showed high technical and clinical success rates of EUS-HGS, making it a feasible and effective alternative to ERCP. The ongoing development of dedicated devices and techniques is expected to make EUS-HGS more accessible and safer for patients in need of biliary drainage.

Initial clinical experience with durvalumab plus tremelimumab in patients with unresectable hepatocellular carcinoma in real‑world practice.

Although durvalumab plus tremelimumab (Dur/Tre) has been approved as first-line therapy for patients with unresectable hepatocellular carcinoma (u-HCC), its outcomes in real-world clinical practice are unclear. The present study aimed to evaluate the efficacy and safety of Dur/Tre treatment. This multicenter study was conducted between March 2023 and January 2024, and included 120 patients with u-HCC treated with Dur/Tre. Among the patients, 44 had no history of systemic treatment. Progression-free survival (PFS), therapeutic response and adverse events (AEs) were assessed. The objective response rate (ORR) and disease control rates (DCR) were 15.8 and 53.3%, respectively. The median PFS was 3.9 months. The incidence rates of AEs of any grade and those grade 3 or higher were 83.3 and 36.7%, respectively. Liver injury was the most frequent AE of any grade and grade 3 or higher. Although there was no significant difference in ORR and PFS between the first and later line groups (ORR 15.8 vs. 15.7%, P=0.986; PFS 4.5 vs. 3.6 months, P=0.213), there was a significant difference in DCR between the two groups (65.8 vs. 45.9%, P=0.034). No significant differences were noted between the first- and later-line treatment groups regarding the incidence rate of AEs. Decision tree analysis revealed that poor liver function and advanced age were significant variables for discontinuation owing to AEs. In conclusion, Dur/Tre as first-line therapy had better disease control responses compared with later-line therapy; however, this regimen should be carefully administered to patients with deteriorating hepatic function or advanced age.

Accuracy assessment of patient safety incident (PSI) codes and present-on-admission (POA) indicators: a cross-sectional analysis using the Patient Safety Incidents Inquiry (PSII) in Korea

BackgroundAmong the various methods used, administrative data collected for claims and billing purposes, such as diagnosis codes and present-on-admission (POA) indicators, can easily be employed to assess patient safety status. However, it is crucial that administrative data be accurate to generate valid estimates of adverse event (AE) occurrence. Thus, we aimed to evaluate the accuracy of diagnosis codes and POA indicators in patients with confirmed AEs in the hospital admission setting.MethodsWe analysed the diagnosis codes of 1,032 confirmed AE cases and 6,754 non-AE cases from the 2019 Patient Safety Incidents Inquiry, which was designed as a cross-sectional study, to determine their alignment with the Korean Patient Safety Incidents (PSIs) Code Classification System. The unit of analysis was the individual case rather than the patient, because two or more AEs may occur in one patient. We examined whether the primary and secondary diagnostic codes had PSIs codes matching the AE type and checked each PSI code for whether the POA indicator had an ‘N’ tag. We reviewed the presence of PSI codes in patients without identified AEs and calculated the correlation between the AE incidence rate and PSI code and POA indicator accuracy across 15 hospitals.ResultsNinety (8.7%) of the AE cases had PSI codes with an ‘N’ tag on the POA indicator compared to 294 (4.4%) of the non-AE cases. Infection- (20.4%) and surgery/procedure-related AEs (13.6%) had relatively higher instances of correctly tagged PSI codes. We did not identify any PSI codes for diagnosis-related incidents. While we noted significant differences in AE incidence rates, PSI code accuracy, and POA indicator accuracy among the hospitals, the correlations between these variables were not statistically significant.ConclusionCurrently, PSI codes and POA indicators in South Korea appear to have low validity. To use administrative data in medical quality improvement activities such as monitoring patient safety levels, improving the accuracy of administrative data should be a priority. Possible strategies include targeted education on PSI codes and POA indicators and introduction of new evaluation indicators regarding the accuracy of administrative data.

Upadacitinib for axial spondyloarthritis: a meta-analysis of efficacy and safety.

To explore the effectiveness and safety of upadacitinib for managing axial spondyloarthritis. Four databases (PubMed, EMBASE, Cochrane, and Web of Science) were applied to search randomized controlled trials (RCTs) for assessing upadacitinib treatment for axial spondyloarthritis published until January 2024. Five RCTs involving 1,246 participants were included. The upadacitinib group had significantly higher percentages of participants achieving Assessment of spondyloarthritis international society (ASAS) 20, ASAS40, ASAS partial remission, Bath ankylosing spondylitis disease activity index (BASDAI) 50, Ankylosing Spondylitis Disease Activity Score (ASDAS) low disease activity, ASDAS inactive disease, ASDAS clinically important improvement, and ASDAS major improvement, except for Work Productivity and Activity Impairment (WPAI) absenteeism. Obvious improvements were observed in the upadacitinib group for ASDAS (CRP), BASDAI, Modified BASDAI, Bath Ankylosing Spondylitis Functional Index (BASFI), Canadian Spondyloarthritis Research Consortium (SPARCC) MRI spine, SPARCC MRI sacroiliac joint, Ankylosing Spondylitis Quality of Life (ASQoLS), ASAS Health Index, Bath Ankylosing Spondylitis Metrology Index (BASMI), Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), Total Back Pain, Nocturnal Back Pain, WPAI overall work impairment, WPAI presenteeism, and WPAI activity impairment. Adverse events (AEs) and serious adverse events (SAEs) incidence rates showed no significant difference differ between upadacitinib and placebo groups. Subgroup analysis revealed that disease subtype and age did not significantly affect efficacy, and upadacitinib demonstrated comparable efficacy to adalimumab for axial spondyloarthritis. Upadacitinib exhibited satisfactory efficacy in treating axial spondyloarthritis, reducing disease activity and significantly enhancing patients' physical function, emotional well-being, and social engagement. This meta-analysis offers robust evidence supporting upadacitinib as a new treatment for axial spondyloarthritis patients.

Skeletonized Versus Pedicled Harvesting of the Internal Thoracic Artery and Long-Term Clinical Outcomes in Coronary Artery Bypass Surgery.

The internal thoracic artery (ITA) is the most important conduit for coronary artery bypass grafting. Recent evidence suggests that skeletonized ITA harvesting yields long-term outcomes inferior to those of pedicled harvesting. The aim was to investigate the impact of the ITA harvesting method on 10-year mortality and major adverse cardiovascular events. In this observational cohort study, we identified all patients from the SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) register who underwent isolated coronary artery bypass grafting using at least 1 ITA at Karolinska University Hospital from 2012 to 2021. The main outcome was all-cause mortality, and the secondary outcomes were a combination of myocardial infarction, repeat revascularization, heart failure, and stroke. Outcomes were ascertained using national health data registers and compared between the skeletonized and pedicled groups using weighted flexible parametric survival models. Among 3267 patients, 1657 (51%) underwent pedicled ITA harvesting and 1610 (49%) underwent skeletonized ITA harvesting. The patients' mean age was 66 years, and 15% were women. The weighted all-cause mortality incidence rate in the pedicled versus skeletonized ITA group was 2.6% (95CI, 2.2%-3.0%) versus 2.6% (95% CI, 2.2%-3.1%), respectively (hazard ratio (HR), 1.01 [95% CI, 0.81-1.27]). The weighted major adverse cardiovascular events incidence rate was 7.8% (95% CI, 7.1%-8.6%) versus 7.5% (95% CI, 6.7%-8.4%), respectively (HR, 0.94 [95% CI, 0.82-1.08]). We found no significant differences in all-cause mortality or major adverse cardiovascular events rates between the 2 ITA harvesting methods.

Efficacy and Safety of Tofacitinib in Ankylosing Spondylitis by Baseline C-Reactive Protein Level: Post Hoc Analysis of Phase II and Phase III Clinical Trials.

This post hoc analysis assessed the effect of baseline C-reactive protein (CRP) on the efficacy and safety of tofacitinib (TOF) use in ankylosing spondylitis (AS), as well as patient-reported outcomes (PROs). Phase II (ClinicalTrials.gov: NCT01786668) and phase III (ClinicalTrials.gov: NCT03502616) data from patients with active AS were used. Endpoints (weeks 12, 16, and 48), including 20% and 40% improvement in Assessment of SpondyloArthritis international Society (ASAS), AS Disease Activity Score with CRP low disease activity, 50% improvement in Bath AS Disease Activity Index (BASDAI50), and PROs (pain and fatigue), were stratified by baseline CRP (mg/L) as follows: < 5 (normal), ≥ 5 (elevated), < 10, and ≥ 10. Safety outcomes were evaluated between < 5 and ≥ 5 mg/L subgroups. Overall, 372 patients were included (69.6% ≥ 5mg/L; 50.8% ≥ 10 mg/L). At baseline in the < 5mg/L group, more placebo-treated than TOF-treated patients received concomitant nonsteroidal antiinflammatory drugs (NSAIDs) or sulfasalazine (SSZ). Week 12 efficacy and PRO responses were generally higher for TOF vs placebo, regardless of baseline CRP. The treatment effect (placebo-adjusted response) at week 12 was generally numerically higher in ≥ 5 mg/L and ≥ 10 mg/L vs < 5 mg/L and < 10 mg/L groups. Incidence rates for treatment-emergent adverse events (TEAEs) and "all infections" were numerically higher for TOF vs placebo in patients in the < 5 mg/L group, but similar for TOF vs placebo in patients in the ≥ 5 mg/L group. Regardless of baseline CRP, TOF was more efficacious vs placebo at week 12. The placebo-adjusted efficacy and PRO responses were generally numerically higher in patients with CRP ≥ 5 mg/L and ≥ 10 mg/L vs < 5 mg/L and < 10 mg/L. The higher concomitant NSAID/SSZ exposure may have improved efficacy responses in the baseline < 5 mg/L placebo group, and ultimately affected the TOF treatment effect. Safety was consistent with previous studies of TOF use in AS, with numerically higher incidence rates for TEAEs and "all infections" for TOF vs placebo in patients with CRP < 5 mg/L.

Transarterial chemoembolization combined with donafenib or lenvatinib as first-line treatment for unresectable hepatocellular carcinoma: A single-center real-world retrospective study.

e16137 Background: Combined Transarterial chemoembolization (TACE) with tyrosine kinase inhibitor (TKI) treatment has been proven to be beneficial. This study aimed to retrospectively compare the efficacy and safety of Donafenib (DON)-TACE versus Lenvatinib (LEN)-TACE as first-line treatment for unresectable hepatocellular carcinoma (uHCC). Methods: From May 2020 to May 2023, a retrospective analysis was conducted on the clinical data of 93 patients with previously untreated uHCC who underwent treatment at the department of Interventional Radiology of the Third Affiliated Hospital of Sun Yat-sen University. Among them, 49 were in the DON-TACE group and 44 in the LEN-TACE group. The primary endpoint was progression-free survival (PFS) according to mRECIST, and the secondary endpoints included objective response rate (ORR), disease control rate (DCR), and safety outcome. Results: As of the data cut-off date Aug 26, 2023, the median PFS was 221 days (95% CI 141–366) in the DON-TACE group and 173 days (95% CI 108–215) in the LEN-TACE group (HR = 0.783, 95% CI 0.462–1.325, P = 0.362).ORR and DCR of the DON-TACE group were 55.1% (95% CI 40.23–69.33) and 75.51% (95% CI 61.13–86.66), respectively, while those of the LEN-TACE group were 61.36% (95% CI 45.49–75.64) and 81.82% (95% CI 67.29–91.81). No significant difference was observed either in ORR(P = 0.689) or DCR(P = 0.627) between the two groups. The incidence rates of total adverse events for any grade (85.71% vs 100.00%, P = 0.027) and ≥Grade 3 (22.496% vs 45.45%, P = 0.019) were significantly lower in the DON-TACE group. In addition, the incidence rates of AST increased (27.27% vs 56.82%, P = 0.005), diarrhea (6.12% vs 25.00%, P = 0.011), vomiting (0% vs 40.91%, P &lt; 0.001), proteinuria (0% vs 18.18%, P = 0.011), gastrointestinal hemorrhage (0% vs 13.64%, P = 0.048) and hypertension (2.04% vs 36.36%, P &lt; 0.001) for any grade were also significantly lower in the DON-TACE group. Conclusions: DON-TACE and LEN-TACE showed comparable efficacy as first-line therapies for uHCC patients. DON-TACE demonstrated a lower incidence of severe adverse events.

Background Rates of Adverse Events of Special Interest for COVID-19 Vaccine Safety Monitoring in South Korea

Objectives: This study aimed to estimate background incidence rates (IR) for adverse events of special interest (AESI) associated with COVID-19 vaccines in South Korea. Methods: We used data from the Korean National Health Insurance Service-National Sample Cohort from January 1, 2015 to December 31, 2019, with IR calculated annually. Eight AESIs including acute myocarditis, acute pericarditis, acute disseminated encephalomyelitis (ADEM), acute transverse myelitis (ATM), encephalitis, anaphylaxis, Bell’s palsy, and lymphadenitis were evaluated. Two operational strategies were implemented: a broad definition using ICD-10 codes for primary or secondary diagnoses to enhance sensitivity, and a narrow definition integrating ICD-10 codes with procedure and drug codes for enhanced accuracy and specificity. IR was calculated by dividing the number of incident cases by the total person-time at risk, with separate analyses by sex and age. Results: During the study period, the incidence of anaphylaxis, Bell’s palsy, and lymphadenitis under the broad definition continued to increase. Under the narrow definition, there were no reported cases of acute myocarditis or Bell’s palsy from 2015 to 2019. Additionally, the incidence rates for acute pericarditis, ADEM, ATM, encephalitis, anaphylaxis, and lymphadenitis were lower than those calculated under the broad definition. Males generally had higher rates, except for Bell’s palsy and lymphadenitis. Most AESIs were more common in individuals aged 65 and older, whereas ADEM and lymphadenitis were higher in children aged 0-19 years. Conclusions: Variability in AESI rates emphasizes the importance of considering definitions and demographics when establishing background rates for surveillance, which is a critical aspect of monitoring vaccine safety.

Effects of NEAT1 levels on cardiovascular events and prognosis in diabetic nephropathy patients undergoing peritoneal dialysis.

The purpose of this study was to provide observational indicators for clinically predicting cardiovascular events in patients with diabetic nephropathy (DN) undergoing peritoneal dialysis by determining the effects of nuclear enriched abundant transcript 1 (NEAT1) levels on the cardiovascular events and prognosis in DN patients receiving continuous ambulatory peritoneal dialysis (CAPD). A retrospective analysis was conducted on the data of 80 DN patients undergoing CAPD. Patients were assigned to NEAT1 high expression group and NEAT1 low expression group. NEAT1 had a substantially increased expression in the serum of DN patients, and it could serve as a potential biomarker for predicting the development of DN. Patients with highly expressed NEAT1 had an higher level of high-sensitivity C-reactive protein (hs-CRP), larger cardiac structural parameters left ventricular end-diastolic diameter (LVED), left ventricular end-systolic diameter (LVESD), interventricular septal diameter (IVSD) and left ventricular posterior wall diameter (LVPWD), but a notably lower cardiac function evaluation indicator left ventricular ejection fraction (LVEF) than those with lowly expressed NEAT1. The coefficient (r) of correlation between NEAT1 and hs-CRP level was 0.3585 (P=0.0011). The incidence rates of acute myocardial infarction, congestive heart failure and angina in NEAT1 high expression group were higher than those in NEAT1 low expression group. Patients with NEAT1 high expression exhibited a higher mortality rate than NEAT1 low expression group. With the increase in NEAT1 levels, the level of hs-CRP rose in DN patients undergoing CAPD. A higher expression level of NEAT1 indicates poorer cardiac function, higher incidence rates of cardiovascular adverse events and a poorer prognosis in diabetics undergoing CAPD.

Can adjuvant immune checkpoint inhibitors improve the long-term outcomes of hepatocellular carcinoma with high-risk recurrent factors after liver resection? A meta-analysis and systematic review

BackgroundAdministering adjuvant therapy following liver resection is crucial for patients with hepatocellular carcinoma (HCC) exhibiting high-risk recurrence factors. Immune checkpoint inhibitors (ICIs) are effective against unresectable HCC; however, their effectiveness and safety for this specific patient group remain uncertain.MethodsWe conducted an extensive literature search across four scholarly databases to identify relevant studies. Our primary endpoints were overall survival (OS), recurrence-free survival (RFS), and adverse events (AEs). OS and RFS were quantified using hazard ratios (HRs), whereas the 1-, 2-, and 3-year OS and RFS rates were expressed as risk ratios (RRs). Additionally, the incidence of AEs was calculated.ResultsOur meta-analysis included 11 studies (N = 3,219 patients), comprising two randomized controlled trials (RCTs) and nine retrospective studies. Among these, eight studies reported HRs for OS, showing a statistically significant improvement in OS among patients receiving adjuvant ICIs (HR, 0.60; 95% confidence interval [CI], 0.45–0.80; p &amp;lt; 0.0001). All included studies reported HRs for RFS, indicating a favorable impact of adjuvant ICIs (HR, 0.62; 95% CI, 0.52–0.73; p &amp;lt; 0.0001). Moreover, aggregated data demonstrated improved 1- and 2-year OS and RFS rates with adjuvant ICIs. The incidence rate of AEs of any grade was 0.70 (95% CI, 0.49–0.91), with grade 3 or above AEs occurring at a rate of 0.12 (95% CI, 0.05–0.20).ConclusionAdjuvant ICI therapy can enhance both OS and RFS rates in patients with HCC exhibiting high-risk recurrence factors, with manageable AEs.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/#recordDetails PROSPERO, identifier CRD42023488250.
