Introduction: Intracerebral hemorrhage (ICH) occurs in 20-30% of the stroke patients undergoing endovascular therapy (EVT). However, there is conflicting evidence regarding the effect of asymptomatic ICH (aICH) on post-EVT outcomes. Methods: In this post-hoc analysis of our multi-center, prospective, “Blood Pressure after Endovascular Therapy (BEST)” study, we determined the rates of patients with aICH and symptomatic ICH (sICH; any ICH associated with ≥4 points deterioration in the baseline NIH Stroke scale). Their associations with a primary outcome of 90-day modified Rankin Scores (mRS) 0-2 vs 3-6 and early neurological recovery (ENR; NIHSS of 0-1 or ≥8-point improvement at 24 hours from baseline) was determined using univariable and multivariable logistic regression models (adjusted for age, NIH stroke scale, ASPECT score, age, thrombolytic administration, and successful recanalization defined as mTICI ≥2b). Results: Of 485 patients included in BEST at 12 comprehensive stroke centers across the US, 446 patients had a 90-day follow-up available. Of these, 92 (20.6%) developed aICH and 18 (4%) developed sICH. The aICH was not associated with worse 90-day outcome or lower ENR (OR 1.19 [0.74-1.88], p=0.45, aOR 1.19 [0.69-2.06], p= 0.53 for 90-day mRS 3-6; OR 0.77 [0.48-1.23], p=0.30, aOR 0.72 [0.43-1.22] for ENR).A higher proportion of patients with aICH had mTICI ≥2b compared to those without any ICH (97%vs 87%, p=0.01, Table). The aICH was not associated with 90-day outcome or ENR in patients with mTICI ≥2b (OR 1.28 [0.79-2.08], p=0.32 for 90-day mRS 3-6; OR 0.89 [0.69-1.12], p=0.14 for ENR). Conclusion: We found insufficient evidence that aICH associated with worse outcomes in EVT-treated patients, including those with successful recanalization. Interestingly, aICH was more frequent in patients with successful recanalization. Further validation of our findings in other large cohort studies of EVT-treated patients is warranted.

BackgroundIntracerebral hemorrhage (ICH) occurs in ~20%–30% of stroke patients undergoing endovascular therapy (EVT). However, there is conflicting evidence regarding the effect of asymptomatic ICH (aICH) on post-EVT outcomes. We sought to evaluate the effect of aICH on immediate and 90-day post-EVT neurological outcomes.MethodsIn this post-hoc analysis of the multicenter, prospective Blood Pressure after Endovascular Therapy (BEST) study we identified subjects with ICH following EVT. This population was divided into no ICH, aICH, and symptomatic ICH (sICH). Associations with 90-day modified Rankin Scale (mRS) dichotomized by functional independence (0–2 vs 3–6) and early neurological recovery (ENR) were determined using univariate/multivariate logistic regression models.ResultsOf 485 patients enrolled in BEST, 446 had 90-day follow-up data available. 92 (20.6%) developed aICH, and 18 (4%) developed sICH. Compared with those without ICH, aICH was not associated with worse 90-day outcome or lower ENR (OR 0.84 [0.53–1.35], P=0.55, aOR 0.84 [0.48–1.44], P=0.53 for 90-day mRS 0–2; OR 0.77 [0.48–1.23], P=0.34, aOR 0.72 [0.43–1.22] for ENR). aICH was not associated with 90-day outcome or ENR in patients with mTICI ≥2 b (OR 0.78 [0.48–1.26], P=0.33 for 90-day mRS 0–2; OR 0.89 [0.69–1.12], P=0.15 for ENR). A higher proportion of patients with aICH had mTICI ≥2 b than those without ICH (97%vs 87%, P=0.01).ConclusionsaICH was not associated with worse outcomes in patients with large-vessel stroke treated with EVT. aICH was more frequent in patients with successful recanalization. Further validation of our findings in large cohort studies of EVT-treated patients is warranted.

Abstract Objective It is unclear whether relatively low glycated haemoglobin (HbA1c) levels are beneficial or harmful for the long-term health outcomes among people without diabetes. We aimed to investigate the association between low HbA1c levels and mortality among the US general population. Methods This study includes a nationally representative sample of 39 453 US adults from the National Health and Nutrition Examination Surveys 1999–2014, linked to mortality data through 2015. We employed the parametric g-formula with pooled logistic regression models and the ensemble machine learning algorithms to estimate the time-varying risk of all-cause and cardiovascular mortality by HbA1c categories (low, 4.0 to <5.0%; mid-level, 5.0 to <5.7%; prediabetes, 5.7 to <6.5%; and diabetes, ≥6.5% or taking antidiabetic medication), adjusting for 72 potential confounders including demographic characteristics, lifestyle, biomarkers, comorbidities and medications. Results Over a median follow-up of 7.5 years, 5118 (13%) all-cause deaths, and 1116 (3%) cardiovascular deaths were observed. Logistic regression models and machine learning algorithms showed nearly identical predictive performance of death and risk estimates. Compared with mid-level HbA1c, low HbA1c was associated with a 30% (95% CI, 16 to 48) and a 12% (95% CI, 3 to 22) increased risk of all-cause mortality at 5 years and 10 years of follow-up, respectively. We found no evidence that low HbA1c levels were associated with cardiovascular mortality risk. The diabetes group, but not the prediabetes group, also showed an increased risk of all-cause mortality. Conclusions Using the US national database and adjusting for an extensive set of potential confounders with flexible modelling, we found that adults with low HbA1c were at increased risk of all-cause mortality. Further evaluation and careful monitoring of low HbA1c levels need to be considered.

ObjectiveTo compare the efficacy of endovascular therapy (EVT) with that of medical treatment in ’real-world ’patients with M2 occlusion.MethodsThis was a post hoc analysis of the Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism Japan Registry 2. Among 2420 patients in the registry, we evaluated patients with isolated M2 occlusion and those with functional independence before the stroke. Multivariable logistic regression analysis was used to evaluate and compare clinical outcomes between EVT and medical treatment. Additional propensity score-matched (PSM) analyses were performed. We performed subgroup analyses of the primary outcome (modified Rankin Scale score 0–2 at 90 days) using forest plots of treatment effects.ResultsOverall, 372 patients with M2 occlusion (n=184 EVT; n=188, medical treatment) were evaluated. The EVT group had a higher baseline National Institutes of Health Stroke Scale score (median (IQR), 15 [9–19] vs 10 [5–16]) and earlier onset to hospital door time (110 [50–258] vs 150 [60–343] min) than the medical treatment group. After adjustment, EVT was significantly associated with higher odds of primary outcome (adjusted OR=2.09; 95% CI 1.26 to 3.47) and lower odds of mortality at 90 days (adjusted OR= 0.27; 95% CI 0.08 to 0.93). After PSM analyses (184 patients were 1:1 matched with each group), EVT was effective and safe relative to medical treatment. Effects favoring EVT were present in several subgroups of interest.ConclusionIn patients with M2 occlusion, our registry suggests that EVT is effective and safe.

Introduction: Previous studies have shown an elevated risk of MI (MI) in patients with symptomatic intracranial atherosclerotic disease (sICAD), but the mediators of increased risk of MI or death in these patients remain uncertain. We aim to determine risk factors associated with MI or death in patients with symptomatic ICAD. Methods: Patients enrolled in SAMMPRIS had sICAD and were randomized to aggressive medical management (AMM) vs. stenting and AMM. The primary outcome of this post-hoc analysis is MI or vascular death within 2 years of follow-up. We excluded patients who were lost to follow up, had a stroke during follow up, had non-vascular death or death within 30 days of stenting. Patients meeting the inclusion criteria were divided into two groups: those with vs. those without the primary outcome. We used binary logistic regression to determine predictors of incident MI or death within 2 years. Results: Of the 451 patients enrolled in SAMMPRIS, 350 patients met the inclusion criteria (reasons for exclusion: 4 deaths occurring within 30 days of stenting, 63 with ischemic stroke, 6 with symptomatic hemorrhage, 7 patients with non-cardiovascular death within 2 years, and 21 lost to follow up). At 2 years, 17 patients (4.9%) had MI/death; 10 patients had MI and 7 had cardiovascular deaths. In a multivariable model, factors associated with MI/death were: history of coronary artery disease (adjusted OR 3.19, 95% CI 1.14 - 8.93, p = 0.027) and systolic blood pressure (adjusted OR per 10 mm increase 1.20, 95% CI 0.98 - 1.44, p = 0.080). This risk was abut 24% with both predictors present and 2.8% with them absent (Figure). Conclusion: Higher systolic blood pressure and pre-existing cardiovascular disease were independently associated with incident MI or vascular death in patients with sICAD, despite medical management. Further studies are needed to confirm this association and test interventions to reduce this risk.

Aim: To identify demographic predictors of patients who miss oncology follow-up, considering that missed follow-up has not been well studies in cancer patients. Methods: Patients with solid tumors diagnosed from 2007 to 2016 were analyzed (n = 16,080). Univariate and multivariable logistic regression models were constructed to examine predictors of missed follow-up. Results: Our study revealed that 21.2% of patients missed ≥1 follow-up appointment. African–American race (odds ratio [OR] 1.33; 95% CI: 1.17–1.51), Medicaid insurance (OR 1.59; 1.36–1.87), no insurance (OR 1.66; 1.32–2.10) and rural residence (OR 1.78; 1.49–2.13) were associated with missed follow-up. Conclusion: Many cancer patients miss follow-up, and inadequate follow-up may influence cancer outcomes. Further research is needed on how to address disparities in follow-up care in high-risk patients.

Abstract Objectives Hispanics are disproportionally affected by obesity, cancer, and other obesity-related chronic diseases. Building a Healthy Temple (BHT) was a multi-component, faith-based lifestyle intervention implemented in 27 low-income, predominately-Hispanic congregations in San Antonio, TX between 2012 and 2017. One aim of BHT was to assess program effectiveness at improving health-conducive church environment/policy and sustainability of these improvements at follow-up. Methods A key macro-level program component of BHT was the formation of a Health Ministry Committee to initiate church-wide health-conducive environment/policy changes. The Congregational Health Index (CHI) was used to assess church nutrition (17 items) and physical activity (PA, 5 items) environment/policy at baseline, end of program, and follow-up (6 months or more post-intervention). Data were expressed as % of the maximum scores. Friedman test and post hoc analysis were performed with Wilcoxon signed-rank tests and significance of pairwise comparisons, adjusted with Bonferroni correction. Results Eighteen churches completed all 3 CHI assessments. Percentage of total nutrition and PA environment/policy scores for baseline, end of program, and follow-up were 38% (35–45), 64% (53–75), and 69% (64–77), respectively. Post hoc analysis shows significant improvements in nutrition and PA environment/policy scores at end of program (Z = –3.73, P < 0.001) and follow-up (Z = –3.73, P < 0.001) as compared to baseline, as well as significantly higher scores at follow-up compared to end of program (Z = –3.18, P = 0.001). Conclusions Study findings reveal the importance of utilizing congregation-wide macro-level interventions to create health-conducive enviroment/policy changes to facilitate and sustain healthy lifestyle changes in predominately-Hispanic faith community settings.

Vaccine Information

There is a critical need for the public to have trusted sources of vaccine information. A longitudinal online study assessed trust in COVID-19 vaccine information from 10 sources. A factor analysis for data reduction revealed two factors. The first factor contained politically conservative sources (PCS) of information. The second factor included eight news sources representing mainstream sources (MS). Multivariable logistic regression models were used. Trust in Dr. Fauci was also examined. High trust in MS was associated with intention to encourage family members to get COVID-19 vaccines, altruistic beliefs that more vulnerable people should have vaccine priority, and belief that racial minorities with higher rates of COVID-19 deaths should have priority. High trust in PCS was associated with intention to discourage friends from getting vaccinated. Higher trust in PCS was also associated with participants more likely to disagree that minorities with higher rates of COVID-19 deaths should have priority for a vaccine. High trust in Dr. Fauci as a source of COVID-19 vaccine information was associated with factors similar to high trust in MS. Fair, equitable, and transparent access and distribution are essential to ensure trust in public health systems’ abilities to serve the population.

Abstract Background and Aims There is paucity of evidence on the reversibility of Crohn’s disease [CD]-related strictures treated with therapies. We aimed to describe the clinical and endoscopic outcomes of CD patients with non-passable strictures. Methods This was a post-hoc analysis of three large CD clinical trial programmes examining outcomes with infliximab, ustekinumab, and azathioprine, which included data on 576 patients including 105 with non-passable strictures and 45 with passable strictures, as measured using the Simple Endoscopic Score for Crohn’s Disease [SES-CD]. The impact of non-passable strictures on achieving clinical remission [CR] and endoscopic remission [ER] was assessed using multivariate logistic regression models. CR was defined as a Crohn’s Disease Activity Index [CDAI] <150, clinical response as a CDAI reduction of ≥100 points, and ER as SES-CD score <3. Results After 1 year of treatment, patients with non-passable strictures demonstrated the ability to achieve passable or no strictures in 62.5% of cases, with 52.4% and 37.5% attaining CR and ER, respectively. However, patients with non-passable strictures at baseline were less likely to demonstrate symptom improvement compared with those with passable or no strictures, with reduced odds of 1-year CR (adjusted odds ratio [aOR] 0.17, 95% CI 0.03–0.99, p = 0.048). No significant differences were observed between patients with non-passable strictures at baseline and those with passable or no strictures in rates of ER [aOR 0.82, 95% CI 0.23–2.85, p = 0.751] at 1 year. Conclusions Patients with non-passable strictures can achieve symptomatic and endoscopic remission when receiving therapies used to treat CD, although they are less likely to obtain CR compared with patients without non-passable strictures. These findings support the importance of balancing the presence of non-passable strictures in trial arms.

Abstract Purpose To explore the potential correlation between baseline interleukin (IL) values and overall survival or objective response in patients with hepatocellular carcinoma (HCC) receiving sorafenib. Methods A subset of patients with HCC undergoing sorafenib monotherapy within a prospective multicenter phase II trial (SORAMIC, sorafenib treatment alone vs. combined with Y90 radioembolization) underwent baseline IL-6 and IL-8 assessment before treatment initiation. In this exploratory post hoc analysis, the best cut-off points for baseline IL-6 and IL-8 values predicting overall survival (OS) were evaluated, as well as correlation with the objective response. Results Forty-seven patients (43 male) with a median OS of 13.8 months were analyzed. Cut-off values of 8.58 and 57.9 pg/mL most effectively predicted overall survival for IL-6 and IL-8, respectively. Patients with high IL-6 (HR, 4.1 [1.9–8.9], p < 0.001) and IL-8 (HR, 2.4 [1.2–4.7], p = 0.009) had significantly shorter overall survival than patients with low IL values. Multivariate analysis confirmed IL-6 (HR, 2.99 [1.22–7.3], p = 0.017) and IL-8 (HR, 2.19 [1.02–4.7], p = 0.044) as independent predictors of OS. Baseline IL-6 and IL-8 with respective cut-off values predicted objective response rates according to mRECIST in a subset of 42 patients with follow-up imaging available (IL-6, 46.6% vs. 19.2%, p = 0.007; IL-8, 50.0% vs. 17.4%, p = 0.011). Conclusion IL-6 and IL-8 baseline values predicted outcomes of sorafenib-treated patients in this well-characterized prospective cohort of the SORAMIC trial. We suggest that the respective cut-off values might serve for validation in larger cohorts, potentially offering guidance for improved patient selection.

AbstractWe evaluated the 6-year incidence and risk factors of pterygium in a multi-ethnic Asian population. Participants who attended the baseline visit of the Singapore Epidemiology of Eye Diseases Study (year 2004–2011) and returned six years later, were included in this study. Pterygium was diagnosed based on anterior segment photographs. Incident pterygium was defined as presence of pterygium at 6-year follow-up in either eye, among individuals without pterygium at baseline. Multivariable logistic regression models were used to determine factors associated with incident pterygium, adjusting for baseline age, gender, ethnicity, body mass index, occupation type, educational level, income status, smoking, alcohol consumption, presence of hypertension, diabetes and hyperlipidemia. The overall age-adjusted 6-year incidence of pterygium was 1.2% (95% confidence interval [CI] 1.0–1.6%); with Chinese (1.9%; 95% CI 1.4%-2.5%) having the highest incidence rate followed by Malays (1.4%; 95% CI 0.9%-2.1%) and Indians (0.3%; 95% CI 0.3–0.7%). In multivariable analysis, Chinese (compared with Indians; odds ratio [OR] = 4.21; 95% CI 2.12–9.35) and Malays (OR 3.22; 95% CI 1.52–7.45), male (OR 2.13; 95% CI 1.26–3.63), outdoor occupation (OR 2.33; 95% CI 1.16–4.38), and smoking (OR 0.41; 95% CI 0.16–0.87) were significantly associated with incident pterygium. Findings from this multi-ethnic Asian population provide useful information in identifying at-risk individuals for pterygium.
