Importance Currently, there are no standardized outcome domains or measures in clinical trials for facial aging. Heterogeneity in outcome domains and measurement instruments across clinical trials creates difficulty in directly comparing interventions, determining superior therapies, and developing high-quality meta-analyses. Objective To develop a core outcome set (COS) of essential domains to be reported in clinical trials evaluating the efficacy of interventions for facial aging. Evidence Review PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL were searched from September 2005 to September 2015. An updated search of the same databases was performed from September 2015 to February 2026. Studies were included if (1) they were randomized clinical trial or controlled clinical trial in design, (2) they assessed the efficacy or safety of an intervention for facial aging, (3) they were published in English, and (4) they involved human participants. Complementary sources, including patient interviews, were used to capture further relevant outcomes. Two rounds of Delphi surveys, followed by consensus meetings, were used to identify outcome domains considered most important by both patient and physician stakeholders. Findings The final COS consists of 6 outcome domains: (1) overall convenience of treatment; (2) time to return to normal work and social activity; (3) overall assessment of focused area of treatment (at the point in time when treatment is expected to provide peak benefit); (4) duration of treatment effect; (5) severity of persistent local or systemic adverse events, including pigmentary change, skin texture change, delayed healing, scarring, and serious adverse events; and (6) patient satisfaction with treatment. Conclusions and Relevance The 6 outcome domains identified through a Delphi consensus are recommended for reporting in future facial aging trials to ensure that outcomes that matter most to patients and clinicians are measured and that results are comparable across interventions.

Importance The choice of induction agent during rapid sequence intubation (RSI) of critically ill adults may affect clinical outcomes. Although ketamine and etomidate are frequently used for RSI, their comparative effectiveness remains controversial. Objective To compare the safety of etomidate vs ketamine for emergency RSI in critically ill adults. Design, Setting, and Participants This cohort study used a target trial emulation with observational data collected between March 1, 2022, and April 30, 2024, from 18 emergency departments across Brazil, with data from the Brazilian Airway Registry Cooperation. Adults who underwent RSI and received either etomidate or ketamine as a sole hypnotic agent were included; those with preintubation cardiac arrest or immediate postintubation transfer were excluded. Exposure Administration of etomidate or ketamine as the induction agent for RSI. Main Outcomes and Measures The primary outcome was 28-day in-hospital mortality. Secondary outcomes included 7-day in-hospital mortality, first-attempt intubation success, and major adverse events (new hemodynamic instability, severe hypoxemia, and cardiac arrest) within 30 minutes after intubation. Inverse probability of treatment weighting was used to adjust for confounding. Risk ratios (RRs) and risk differences (RDs) with 95% CIs were used to compare outcomes between groups. Results Among 1810 patients (median age, 64 years [IQR, 50-74 years]; 1048 men [57.9%]), 514 received ketamine and 1296 received etomidate. The median shock index was higher in the ketamine group than the etomidate group (0.81 [IQR, 0.65-1.01] vs 0.76 [IQR, 0.59-0.99]), and preintubation vasopressor use was more common in the ketamine group than the etomidate group (191 of 514 [37.2%] vs 391 of 1296 [30.2%]). Weighted 28-day mortality was higher with etomidate than ketamine (60.5% [95% CI, 57.2%-63.8%] vs 54.4% [95% CI, 45.0%-63.9%]; RR, 1.14 [95% CI, 1.03-1.27]; RD, 7.6% [95% CI, 2.0%-13.3%]). Seven-day mortality was also higher with etomidate than ketamine (35.2% [95% CI, 32.0%-38.3%] vs 30.1% [95% CI, 23.5%-36.7%]; RR, 1.19 [95% CI, 1.04-1.35]). New hemodynamic instability within 30 minutes after intubation was more frequent with ketamine (24.2% [95% CI, 20.4%-28.0%] vs 18.9% [95% CI, 16.7%-21.0%]; RR, 0.78 [0.64-0.95]). There were no statistically significant differences in the other secondary outcomes. Conclusions and Relevance In this cohort study of critically ill adults undergoing RSI, etomidate use was associated with higher in-hospital mortality at 7 and 28 days compared with ketamine. These findings highlight the need for definitive randomized clinical trials to compare both agents.

Abstract Importance and Objective Upadacitinib, an oral, reversible Janus kinase inhibitor, is approved for the treatment of moderate-to-severe Crohn’s disease (CD). Limiting corticosteroid exposure is an important goal in treating CD. This posthoc analysis evaluated the corticosteroid-sparing effects of upadacitinib in patients with CD. Design and Setting This study included pooled data from two phase 3, multicenter, double-blind induction trials and one maintenance trial. Randomization was stratified by corticosteroid use at induction baseline, with a mandatory corticosteroid taper starting at induction week 4. Efficacy was evaluated by baseline corticosteroid use and by achieving corticosteroid-free outcomes through year 2 of maintenance therapy. Safety was also assessed. Results At baseline, 34.7% (234/674) and 35.7% (124/347) of upadacitinib 45 mg and placebo-treated patients were taking corticosteroids, respectively. At induction week 12 and maintenance week 52, higher rates of upadacitinib-treated patients were corticosteroid-free among all patients and among patients with baseline corticosteroid use compared with placebo; upadacitinib-treated patients achieved higher rates of corticosteroid-free outcomes, compared with placebo, including corticosteroid-free clinical remission (stool frequency/abdominal pain score [SF/APS]: 42.7% vs 16.1%; CD activity index [CDAI]: 41.2% vs 23.4%) and corticosteroid-free endoscopic response (37.0% vs 8.1%), with similar results observed among responders to upadacitinib induction therapy at maintenance week 52. Corticosteroid-free outcomes were sustained through year 2 of maintenance therapy. The safety profile was similar to the overall population, with no new safety risks identified. Conclusions and Relevance The results from pivotal studies demonstrated that upadacitinib effectively induced early and sustainable corticosteroid-free clinical remission with a manageable safety profile in patients with moderate-to-severe CD.

ABSTRACT Background Obeticholic acid (OCA) was conditionally approved in 2016 as a second‐line therapy for patients with primary biliary cholangitis (PBC) and incomplete response to ursodeoxycholic acid (UDCA) monotherapy. We aimed to evaluate the impact of OCA add‐on therapy on biochemical outcomes and safety in those patients. Methods We systematically searched MEDLINE, Embase, and Cochrane CENTRAL for papers published up to October 29, 2024, evaluating OCA in patients with PBC at the 12‐month timepoint. Pooled analyses of liver enzymes were performed using the standard mean difference (SMD) and 95% confidence interval (CI) from the OCA baseline. Side effects and the achievement of criteria for adequate response are presented in percentages (95% CI). Results We included 1285 patients from 10 studies, two of which were RCTs. The addition of OCA significantly reduced alkaline phosphatase (ALP) (SMD −0.86; −1.15 to −0.56; p < 0.001) and total bilirubin (SMD −0.29; −0.43 to −0.15; p < 0.001). Overall, 37.23% of the patients (95% CI 31.47–43.39) responded to OCA (POISE criteria). The response rate was greater in the POISE trial results compared with real‐world data (46.15% vs. 30.54%, respectively; p = 0.0089). Pruritus was the most common adverse event (40.23%; 24.65–58.07). Approximately one‐fifth of the patients stopped OCA (18.05%; 12.72–24.99), with pruritus being the main reason for discontinuation (47.70%; 34.15–61.60). Conclusion Adding OCA improves ALP, bilirubin, and biochemical remission rates in patients with PBC who did not respond well to UDCA monotherapy. Real‐world data show an attenuated response. Pruritus is the most common side effect and the leading cause of drug discontinuation.

Abstract Background and Aims The long-term efficacy and safety of upadacitinib in patients with moderate to severe Crohn’s disease (CD) were evaluated in the U-ENDURE Long-Term Extension (LTE) study. Here we report the results after 2 years of total maintenance treatment. Methods U-ENDURE is an ongoing 240-week LTE study conducted at 243 sites across 43 countries (first patient enrolled in LTE 21 March 2019). Patients who completed the 52-week maintenance study continued their previously assigned treatment, once-daily upadacitinib 15 mg or upadacitinib 30 mg. Efficacy was analyzed at week 48 of the LTE; safety was analyzed in the cumulative study population (combined 52 week maintenance and 48 week LTE) and the LTE study population only (cutoff date: 19 December 2023). Results From LTE week 0 to week 48, as-observed efficacy rates for clinical remission (per stool frequency/abdominal pain score, upadacitinib 15 mg: 78.3% to 82.9%; upadacitinib 30 mg: 84.7% to 76.6%; per CD Activity Index, upadacitinib 15 mg: 81.3% to 83.1%; upadacitinib 30 mg: 86.1% to 86.8%), endoscopic response (upadacitinib 15 mg: 59.6% to 67.1%; upadacitinib 30 mg: 71.2% to 69.6%), inflammatory biomarkers, and quality-of-life outcomes remained stable. The safety profile of the cumulative maintenance population observed through LTE week 48 was consistent with previous trials in the upadacitinib CD program. Treatment-emergent adverse event rates for the cumulative maintenance population were 283.1 and 273.4 events/100 patient-years for upadacitinib 15 mg and upadacitinib 30 mg, respectively. Event rates of serious treatment-­emergent adverse events were 16.0 events/100 patient-years for upadacitinib 15 mg and 14.6 events/100 patient-years for upadacitinib 30 mg. The most common adverse events of special interest (≥ 5.0 events/100 patient-years) were hepatic disorder, lymphopenia, creatine phosphokinase elevation, herpes zoster, and anemia. There was 1 treatment-emergent adverse event of suicide leading to death. Conclusion Sustained clinical, endoscopic, quality-of-life, and biomarker outcomes were observed in patients who were initial responders to upadacitinib and completed 2 years of maintenance therapy, with no new safety signals identified.

Abstract Accumulating evidence suggests dysregulated immune checkpoint (IC) signaling can exacerbate COVID-19 severity, but the role of these molecules in the pathogenesis of fatal COVID-19-related diffuse alveolar damage (DAD) remains elusive. Understanding how IC proteins influence acute lung injury due to COVID-19 can provide insights into potential therapeutic strategies to modulate immune responses and improve patient outcomes. Here, in a single-center autopsy cohort, we determined the cellular localization of ICs in lung tissue from cases of fatal COVID-19, DAD-comparators, and non-fibrotic controls by using immunohistochemistry, and investigated their association with clinical outcomes. We expanded our findings by performing analyses of publicly available single-cell RNA sequencing datasets from patients with fatal COVID-19 and non-fibrotic controls. We demonstrated the presence of protein-protein interaction networks of ICs in the lung cellular niche by performing transcriptomic profiling of lung tissue-derived RNA counts from patients with fatal COVID-19. Further, we leveraged data from the largest international, multi-center COVID-19 autopsy cohort and validated that, among patients with fatal COVID-19, those with higher PD-L1/CD274 expression in lung endothelial cells had more rapid clinical deterioration. Lastly, in a cohort of individuals with early COVID-19, IC plasma protein levels were elevated in those with persistent SARS-CoV-2 RNAemia and adverse clinical outcomes. Collectively, our data provide unique pathological insights into the role of IC dysregulation and differential disease severity in COVID-19.

Abstract Background We evaluated the association of achieving endoscopic outcomes at week 12 of induction with improvements in clinical outcomes and quality of life (QoL) at week 52 of maintenance in patients with moderately to severely active Crohn’s disease (CD) treated with upadacitinib (UPA). Methods This post hoc analysis evaluated data from 2 phase 3 induction trials (NCT03345836 and NCT03345849) and 1 maintenance (NCT03345823) trial. Clinical responders to 12-week induction therapy with UPA who also received 52-week maintenance treatment with UPA were included. Endoscopic response, remission, healing, and ulcer-free endoscopy were assessed at week 12. Meaningful improvements in clinical and QoL outcomes were evaluated at week 52. Results A significantly greater proportion of patients who achieved an endoscopic response at the end of induction, compared with patients who did not, attained Crohn’s Disease Activity Index (CDAI) remission (52.0% vs 34.6%; P ≤ .01), corticosteroid-free CDAI remission (50.0% vs 30.9%), Inflammatory Bowel Disease Questionnaire remission (52.6% vs 30.3%), and meaningful improvements in Functional Assessment of Chronic Illness Therapy—Fatigue response (46.7% vs 25.9%), overall work impairment (47.1% vs 26.5%), and daily activity impairment (53.3% vs 34.1%) (all P &lt; .05) at week 52. Similar findings were observed for patients who achieved endoscopic remission, endoscopic healing, and ulcer-free endoscopy at the end of induction vs those who did not. Conclusions Early improvement in endoscopic outcomes after UPA induction treatment was associated with long-term meaningful improvements in clinical outcomes and QoL in patients with CD. Clinical Registration number U-EXCEED induction trial (NCT03345836), U-EXCEL induction trial (NCT03345849), and U-ENDURE maintenance trial (NCT03345823).

Abstract Background Upadacitinib (UPA) is an oral Janus kinase inhibitor approved for the treatment of moderately to severely active Crohn’s disease (CD).1 The U-ENDURE (NCT03345823) maintenance study and long-term extension (LTE) evaluate the long-term efficacy and safety of UPA maintenance therapy. Here, we report the results of the U-ENDURE LTE. Methods Patients (pts) completing the U-ENDURE 52-week (wk) maintenance study were eligible to participate in the LTE and continue their previously assigned treatment (placebo [PBO], UPA 15 mg [UPA15] once daily [QD], or UPA 30 mg [UPA30] QD; blinded until the last pt completed maintenance wk52). Clinical response, clinical remission, endoscopic response, endoscopic remission, as well as high-sensitivity C-reactive protein (hs-CRP) and faecal calprotectin (FCP) were evaluated as-observed up to wk48 of the LTE among pts (PBO [N = 89], UPA15 [N = 107], UPA30 [N = 173]); excluding pts who received open-label UPA30 rescue therapy. Safety was assessed in all pts (PBO [N = 223], UPA15 [N = 221], UPA30 [N = 229]) from wk0 of the maintenance study up to LTE wk204 (cut-off date: 01 Aug 2023). Results At LTE wk0, the SF/APS clinical remission rates were 73.0%, 78.3%, and 80.3% for PBO, UPA15, and UPA30, respectively (Figure 1A). Similar rates were reported at LTE wk0 for CDAI clinical remission (PBO 75.3%, UPA15 81.3%, UPA30 80.9%; Figure 1B) and clinical response (CR-100: PBO 79.5%, UPA15 84.9%, UPA30 84.4%). Rates of clinical remission were stable through wk48 of the LTE. Endoscopic response (PBO 32.9%, UPA15 59.6%, UPA30 66.5%) and remission rates (PBO 27.8%, UPA15 42.4%, UPA30 47.3%) at LTE wk0 were sustained through wk48 with UPA while decreased with PBO (Figure 1C-D). At LTE wk0, the mean [95% CI] change from induction BL in hs-CRP was 1.8 [–0.4, 4.1], –13.2 [–17.9, –8.6], and –12.8 [–16.8, –8.9] for PBO, UPA15, and UPA30, respectively; sustained through wk48. Similar results were observed with FCP (mean [95% CI] change from induction BL: PBO 126 [–103, 356], UPA15 –2946 [–4121, –1772], UPA30 –1871 [–2577, –1165]). Severe adverse events (AEs) and serious AEs were lower with UPA treatment compared with PBO (Table 1). The rates of most AEs of special interest were similar between UPA and PBO; however, numerically higher rates of herpes zoster, adjudicated gastrointestinal perforations, neutropenia, lymphopenia, creatine phosphokinase elevation, and hepatic disorders were reported in pts treated with UPA vs PBO (Table 1). Conclusion In pts completing wk48 of the LTE, sustained efficacy was observed in clinical and endoscopic endpoints with over 2 years of UPA treatment, while maintaining an overall positive safety profile in pts with CD.
