Background: We aim to investigate the effects and safety of clopidogrel plus aspirin in patients with different types of single small subcortical infarction (SSSI) in the Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial.Methods: SSSI was defined as single DWI lesion of ≤2.0 cm. Patients with SSSI were divided into SSSI + PAD (parent artery disease) and SSSI – PAD, according to the stenosis of the parent artery. The efficacy outcome was stroke recurrence during 90-day follow-up. Cox proportional hazards models or logistic regression models were used to assess the interaction of the treatment effects of clopidogrel plus aspirin vs. aspirin alone among patients with and without PAD.Results: Among 338 patients with SSSI included in the subanalysis, 105 were with PAD and 233 without. The efficacy of clopidogrel plus aspirin compared with aspirin alone on any stroke was consistent between patients with [adjusted hazard ratio (HR) 0.84; 95% confidence interval (CI), 0.25–2.75] and without PAD (adjusted HR 1.03; 95% CI, 0.40–2.68, interaction P = 0.83). In patients with SSSI + PAD, the rate of stroke recurrence in those treated with dual antiplatelet therapy and mono antiplatelet therapy was not significantly different (10.9 vs. 13.6%, P = 0.77). The number of bleeding events was similar between the clopidogrel-aspirin group and aspirin group regardless of SSSI + PAD or SSSI – PAD.Conclusions: There was no significant difference in the efficacy of clopidogrel plus aspirin compared with aspirin alone between patients with SSSI + PAD and SSSI – PAD in the CHANCE trial. Studies in other populations and with adequate power are needed to further verify such findings.

Objective: We aim to investigate the effects and safety of clopidogrel plus aspirin in patients with different types of single small subcortical infarction(SSSI) in the Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial. Methods: In this subgroup analysis, SSSI was defined as single DWI lesion of ≤2.0 cm and SSSI with stenosis of any degree of the parent artery was regarded as a SSSI+PAD. We assessed the interaction of the treatment effects of clopidogrel plus aspirin versus aspirin alone among patients with and without PAD. Efficacy was assessed by intention to treat analysis and safety was assessed in the on-treatment population. Results: A total of 338 patients with SSSI were included in the final analysis,105 with SSSI+PAD and 233 SSSI-PAD. In SSSI+PAD patients, 10.9% (5/46) had recurrent stroke in the clopidogrel-aspirin group as compared to 13.6% (8/59) in the aspirin group (adjusted hazard ratio, 0.66; 95% confidence interval, 0.20-2.20; P=0.50). In SSSI-PAD patients, 8.9% (11/124) had recurrent stroke in the clopidogrel-aspirin group as compared 7.3% (8/109) in the aspirin group (adjusted hazard ratio, 1.64; 95% confidence interval, 0.61- 4.38; P=0.32). The number of bleeding events was similar between the clopidogrel-aspirin group and aspirin group regardless of SSSI+PAD or SSSI-PAD. Conclusions: Although dual antiplatelet therapy did not significantly reduce the risk of recurrent stroke than aspirin alone in patients with SSSI. It was potentially beneficial to the patients with SSSI+PAD. Dual antiplatelet treatment did not increase the risk of bleeding in patients with any kind of SSSI.

A Prospective Study

<b><i>Introduction:</i></b> This study aimed to examine whether intraplaque neovascularization (IPN) of carotid plaques, as characterized by contrast-enhanced ultrasound (CEUS), is associated with ischemic stroke recurrence in patients with carotid atherosclerosis. <b><i>Methods:</i></b> We conducted a prospective study of consecutive patients with a recent stroke and at least one atherosclerotic plaque in the carotid artery on the side consistent with symptoms. All patients underwent CEUS after their first admission. IPN was graded on the basis of the presence and location of microbubbles within each plaque. <b><i>Results:</i></b> We eventually included 155 patients, all of whom underwent IPN analysis. After a follow-up of 24 months, we recorded 25 (16.1%) stroke recurrences in the whole population. All the recurrences occurred in patients presenting IPN. There was significant difference in the IPN between the 2 groups (<i>p</i> = 0.002). In the final Cox proportional-hazards multivariable models, IPN of grade 2 was independently associated with the risk of stroke recurrence (HR = 4.535; 95% CI: 1.892–10.870; <i>p</i> = 0.001). This association remained after adjusting for the degree of carotid stenosis (HR = 3.491; 95% CI: 1.410–8.646; <i>p</i> = 0.007). <b><i>Conclusions:</i></b> IPN was an independent predictor of stroke recurrence in patients with a recent ischemic stroke and carotid atherosclerosis. In predicting stroke recurrence, IPN may be an earlier indicator than carotid stenosis and may help stratify the risk of stroke recurrence.

ObjectivesTo establish a new ambulatory blood pressure (ABP) parameter (24-hour ABP profile) and evaluated its performance on stroke outcome in ischaemic stroke (IS) or transient ischaemic attack (TIA) patients.MethodsThe prospective cohort consisted of 1996 IS/TIA patients enrolled for ABP monitoring and a 3-month follow-up for stroke recurrence as outcome. Profile groups of systolic blood pressure (SBP) were identified via an advanced functional clustering method, and the associations of the profile groups and conventional ABP parameters with stroke recurrence were examined in a Cox proportional hazards model.ResultsThree discrete profile groups (n=604, 781 and 611 in profiles 1, 2 and 3, respectively) in 24-hour ambulatory SBP were identified. Profile 1 resembled most to the normal diurnal blood pressure pattern; profile 2 also dropped at night, but climbed earlier and with higher morning surge; while profile 3 had sustained higher nocturnal SBP without significant nocturnal SBP decline. The incidence of stroke recurrence was 2.9%, 3.9% and 5.5% in profiles 1, 2 and 3, respectively. After adjustment for covariates, profile 3 was significantly associated with higher risk of stroke recurrence with profile 1 as reference (HR 1.76, 95% CI: 1.00 to 3.09), while no significant difference was observed between profiles 2 and 1 (HR 1.22, 95% CI: 0.66 to 2.25). None of conventional ABP parameters showed significant associations with the outcome.ConclusionsAmbulatory 24-hour SBP profile is associated with short-term stroke recurrence. Profiles of ABP may help improve identification of stroke recurrence by capturing the additive effects of individual ABP parameters.

Abstract Purpose Colorectal cancer revealed over the last decades a remarkable shift with an increasing proportion of a right- compared to a left-sided tumor location. In the current study, we aimed to disclose clinicopathological differences between right- and left-sided colon cancer (rCC and lCC) with respect to mortality and outcome predictors. Methods In total, 417 patients with colon cancer stage I–IV were analyzed in the present retrospective single-center study. Survival rates were assessed using the Kaplan–Meier method and uni/multivariate analyses were performed with a Cox proportional hazards regression model. Results Our study showed no significant difference of the overall survival between rCC and lCC stage I–IV (p = 0.354). Multivariate analysis revealed in the rCC cohort the worst outcome for ASA (American Society of Anesthesiologists) score IV patients (hazard ratio [HR]: 16.0; CI 95%: 2.1–123.5), CEA (carcinoembryonic antigen) blood level > 100 µg/l (HR: 3.3; CI 95%: 1.2–9.0), increased lymph node ratio of 0.6–1.0 (HR: 5.3; CI 95%: 1.7–16.1), and grade 4 tumors (G4) (HR: 120.6; CI 95%: 6.7–2179.6) whereas in the lCC population, ASA score IV (HR: 8.9; CI 95%: 0.9–91.9), CEA blood level 20.1–100 µg/l (HR: 5.4; CI 95%: 2.4–12.4), conversion to laparotomy (HR: 14.1; CI 95%: 4.0–49.0), and severe surgical complications (Clavien-Dindo III–IV) (HR: 2.9; CI 95%: 1.5–5.5) were identified as predictors of a diminished overall survival. Conclusion Laterality disclosed no significant effect on the overall prognosis of colon cancer patients. However, group differences and distinct survival predictors could be identified in rCC and lCC patients.

The Impact

Data supporting the use of etoposide-based therapy in hemophagocytic lymphohistiocytosis (HLH) arise largely from pediatric studies. There is a lack of comparable data among adult patients with secondary HLH. We conducted a retrospective study to assess the impact of etoposide-based therapy on outcomes in adult secondary HLH. The primary outcome was overall survival. The log-rank test was used to compare Kaplan-Meier distributions of time-to-event outcomes. Multivariable Cox proportional hazards modeling was used to estimate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). Ninety adults with secondary HLH seen between January 1, 2009, and January 6, 2020, were included. Forty-two patients (47%) received etoposide-based therapy, while 48 (53%) received treatment only for their inciting proinflammatory condition. Thirty-three patients in the etoposide group (72%) and 32 in the no-etoposide group (67%) died during follow-up. Median survival in the etoposide and no-etoposide groups was 1.04 and 1.39 months, respectively. There was no significant difference in survival between the etoposide and no-etoposide groups (log-rank <i>p</i> = 0.4146). On multivariable analysis, there was no association between treatment with etoposide and survival (HR for death with etoposide = 1.067, 95% CI: 0.633–1.799, <i>p</i> = 0.8084). Use of etoposide-based therapy was not associated with improvement in outcomes in this large cohort of adult secondary HLH patients.

Abstract Background/Introduction Shockable rhythm after cardiac arrest is highly expected after early initiation of bystander cardiopulmonary resuscitation (CPR) owing to increased coronary perfusion. However, the relationship between bystander CPR and initial shockable rhythm in patients with out-of-hospital cardiac arrest (OHCA) remains unclear. We hypothesized that chest-compression-only CPR (CC-CPR) before emergency medical service (EMS) arrival has an equivalent effect on the likelihood of initial shockable rhythm to the standard CPR (chest compression plus rescue breathing [S-CPR]). Purpose We aimed to examine the rate of initial shockable rhythm and 1-month outcomes in patients who received bystander CPR after OHCA. Methods The study included 59,688 patients (age, ≥18 years) who received bystander CPR after an OHCA with a presumed cardiac origin witnessed by a layperson in a prospectively recorded Japanese nationwide Utstein-style database from 2013 to 2017. Patients who received public-access defibrillation before arrival of the EMS personnel were excluded. The patients were divided into CC-CPR (n=51,520) and S-CPR (n=8168) groups according to the type of bystander CPR received. The primary end point was initial shockable rhythm recorded by the EMS personnel just after arrival at the site. The secondary end point was the 1-month outcomes (survival and neurologically intact survival) after OHCA. In the statistical analyses, a Cox proportional hazards model was applied to reflect the different bystander CPR durations before/after propensity score (PS) matching. Results The crude rate of the initial shockable rhythm in the CC-CPR group (21.3%, 10,946/51,520) was significantly higher than that in the S-CPR group (17.6%, 1441/8168, p&lt;0.0001) before PS matching. However, no significant difference in the rate of initial shockable rhythm was found between the 2 groups after PS matching (18.3% [1493/8168] vs 17.6% [1441/8168], p=0.30). In the Cox proportional hazards model, CC-CPR was more negatively associated with the initial shockable rhythm before PS matching (unadjusted hazards ratio [HR], 0.97; 95% confidence interval [CI], 0.94–0.99; p=0.012; adjusted HR, 0.92; 95% CI, 0.89–0.94; p&lt;0.0001) than S-CPR. After PS matching, however, no significant difference was found between the 2 groups (adjusted HR of CC-CPR compared with S-CPR, 0.97; 95% CI, 0.94–1.00; p=0.09). No significant differences were found between C-CPR and S-CPR in the 1-month outcomes after PS matching as follows, respectively: survival, 8.5% and 10.1%; adjusted odds ratio, 0.89; 95% CI, 0.79–1.00; p=0.07; cerebral performance category 1 or 2, 5.5% and 6.9%; adjusted odds, 0.86; 95% CI, 0.74–1.00; p=0.052. Conclusions Compared with S-CPR, the CC-CPR before EMS arrival had an equivalent multivariable-adjusted association with the likelihood of initial shockable rhythm in the patients with OHCA due to presumed cardiac causes that was witnessed by a layperson.

Objective: The aim of this study was to investigate the clinicopathological prognostic factors of malignant ovarian germ cell tumors (MOGCT) and evaluate the survival trends of MOGCT by histotype. Methods: We extracted data on 1,963 MOGCT cases diagnosed between 2000 and 2014 from the Surveillance, Epidemiology, and End Results (SEER) database and the histological classification of MOGCT, including 5 categories: dysgerminoma, embryonal carcinoma (EC), yolk sac tumor, malignant teratoma, and mixed germ cell tumor. We examined overall and disease-specific survival of the 5 histological types. Kaplan-Meier and Cox proportional hazards regression models were used to estimate survival curves and prognostic factors. We also estimated survival curves of MOGCT according to different treatments. Results: There was a significant difference in prognosis among different histological classifications. Age, histotype, grade, SEER stage, and surgery were independent prognostic factors for survival of patients with MOGCT. For all histotypes, 1-, 3-, and 5-year survival rate estimates were >85%, except for EC, which had the worst outcomes at 1 year (55.6%), 3 years (44.4%), and 5 years (33.3%). In the distant SEER stage, both chemotherapy and surgery were associated with improved survival outcomes compared with surgery- and chemotherapy-only groups. Conclusions: Dysgerminoma patients had the most favorable outcomes, whereas EC patients had the worst survival. A young age, low grade, and surgery were all significant predictors for improved survival. In contrast, a distant SEER stage was a risk factor for poor survival. Chemotherapy combined with surgery contributed to longer survival times of patients with MOGCT in the distant SEER stage.

Abstract Background We aimed to determine whether Plasmodium falciparum (Pf) infection affects age of Kaposi sarcoma-associated herpesvirus (KSHV) seroconversion in Kenyan children. Methods Kenyan children (n=144) enrolled at age one month, from two sites with different levels of malaria transmission (stable/high malaria vs. unstable/low malaria transmission) were followed through 24 months. Plasma was tested for KSHV antibodies using enzyme-linked immunosorbent assay (ELISA) (K8.1 and LANA) and a multiplex bead-based assay (K8.1, K10.5, ORF38, ORF50, and LANA) and whole blood tested for Pf DNA using quantitative-PCR. Cox proportional hazards models were used to assess associations between Pf DNA detection, malaria annualized rate (Pf detections/person-years), and enrollment site (malaria-high vs malaria-low) with time to KSHV seroconversion. Results KSHV seroprevalence was 63% by 2 years of age when assessed by multiplex assay. Children with Pf were at increased hazards of earlier KSHV seroconversion and among children with malaria, the hazard of becoming KSHV seropositive increased significantly with increasing malaria annualized rate. Children from the malaria-high transmission region had no significant difference in hazards of KSHV seroconversion at 12 months but were more likely to become KSHV seropositive by 24 months of age. Discussion Malaria exposure increases the risk for KSHV seroconversion early in life.

3133 Background: The primary objective of EPCCT (phase I and non-randomised phase II trials) is to determine the safety and tolerability of new therapeutic agents. Response rates (RR) in these trials have typically been reported at around 10-15%. Increasingly RR and survival outcomes are now investigated in EPCCT as primary or secondary objectives. Methods: Retrospective data analysis was performed on patients (pts) enrolled onto an EPCCT between January 2018 and December 2019 at The Christie NHS Foundation Trust, UK. Data on demographics, prior systemic treatment, sites of disease, performance status, comorbidities, types of therapy, RR, progression free survival (PFS), and overall survival (OS) were collected. Statistical analyses were performed with univariable and multivariable models. Objective response rate (ORR) was defined as the proportion of pts with complete response (CR) and partial response (PR). Duration of response (DOR) was from initial response to progressive disease (PD). Disease control rate (DCR) was defined as CR+PR+ stable disease (SD). Results: A total of 247 pts were treated across 46 EPCCTs. Median age 61 years; 57% female. Sixty-six percent of pts had ≥2 lines of treatment and the majority were ECOG PS 0/1 (98%). Eighty-one percent of pts had ≥2 sites of metastatic disease, and 13 major tumour types were included. Monotherapy trials (159 pts) were predominantly targeted therapies (TT; 60%), or immunotherapies (IO; 20%). Combination therapy trials (88 pts) were TT-based (68%) or IO-based (32%). Data for RR analyses was available for 231 pts. ORR across all trials was 15% (CR 2%) and DCR was 63%. The median DOR was 8.3 months (mos) (95% CI: 7.0 – 9.7) with 28% of pts responding for >6 mos and 7% for >12 mos. ORR in pooled IO treated pts was 27%, DCR was 65% with sustained response >6 mos seen in 37% of these pts. ORR in pooled TT treated pts was 9.4%, DCR was 60% and sustained response > 6 mos seen in 25% of pts. ORR for IO v TT treated pts was significantly different, p=0.007 (pearson chi square), but no significant difference was seen for DCR. Median PFS for all patients was 5.0 mos (95% CI: 4.1 – 6.0) and OS was 10.4 mos (95% CI: 8.4 – 13.0). OS for those with a PR is not reached (HR for PR v PD, 0.006 (95% CI: 0.002 – 0.18). Pts with SD appear to have significantly better OS compared to those with PD (14.6 v 4.2 mos, HR 0.2 (95% CI: 0.1 – 0.3). Multivariable Cox proportional hazards analysis for OS was significant for male gender (HR 1.9, p=0.002), presence of liver metastasis (HR 2.0, p=0.001), low Hb (HR 0.8, p=0.03) and log (LDH) (HR 1.9, p<0.001). Conclusions: Two-thirds of pts enrolled on EPCCTs benefitted in terms of DCR with significant OS improvement in those with PR and SD. Higher ORR were seen in pts receiving IO-based treatments however DCR was similar in IO and TT pts. Gender, presence of liver metastases, Hb count and LDH level contributed significantly to survival differences.

Introduction: The atherogenicity of residual cholesterol (RC) has been underlined by recent guidelines, which was linked to coronary artery disease (CAD), especially for patients with diabetes mellitus (DM). Hypothesis: This study aimed to examine the prognostic value of plasma RC, clinically presented as triglyceride-rich lipoprotein-cholesterol (TRL-C) or remnant-like lipoprotein particles-cholesterol (RLP-C), in CAD patients with different glucose metabolism status. Methods: Fasting plasma TRL-C and RLP-C levels were directly calculated or measured in 4331 patients with CAD. Patients were followed for incident MACEs for up to 8.6 years and categorized according to both glucose metabolism status [DM, pre-DM, normal glycaemia regulation (NGR)] and RC levels. Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence intervals. Results: During a mean follow-up of 5.1 years, 541 (12.5%) MACEs occurred. The risk for MACEs was significantly higher in patients with elevated RC levels after adjustment for potential confounders. No significant difference in MACEs was observed between pre-DM and NGR groups (p>0.05). When stratified by status of glucose metabolism and RC levels, highest levels of RLP-C, calculated and measured TRL-C were significant and independent predictors of developing MACEs in pre-DM (HR: 2.10, 1.98, 1.92, respectively; all p<0.05) and DM (HR: 2.25, 2.00, 2.16, respectively; all p<0.05). Conclusions: In this large cohort study with long-term follow-up, data firstly demonstrated that higher RC levels were significantly associated with the worse prognosis in DM and pre-DM patients with CAD, suggesting RC might be a target for patients with impaired glucose metabolism.
