Objective: To compare incidence of ischemic stroke, hemorrhagic stroke and all-cause mortality in Korean adults congenital heart disease (ACHD) to that of control and scrutinize risk factors for these outcomes. Methods: Subjects aged over 20 were collected from the Korea National Health Insurance Service from 2006 through 2017. ACHD group as case was extracted from the diagnosis records related to CHD according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD 10). Those without CHD (control group) was selected as 4 controls for each patient through random sampling. We compared incidence rate of ischemic stroke, hemorrhagic stroke and all-cause mortality. Cox proportional hazard models were used to investigate relevant risk factors for each of outcomes. Results: Case and control group were 49,445 and 249,649, respectively. Age-adjusted rates of ischemic stroke, hemorrhagic stroke and all-cause mortality in case was by about 4 times more higher than those of control. Cumulative survival plot demonstrated that ACHD was associated with ischemic stroke (HR 1.31 95% CI 1.25-1.36), hemorrhagic stroke (HR 1.49 95% CI 1.36-1.63), and all-cause mortality (HR 1.41 95% CI 1.35-1.46). Case group was associated with younger age, female, hypertension, diabetes mellitus, coronary artery disease, heart failure, atrial fibrillation (all p <.001). In Cox proportional hazard model for ischemic stroke, diabetes (HR 2.13 95% CI 1.93-2.35) and coararctation of aorta (HR 1.54 95% CI 1.13 - 2.09) carried highest risk. In multivariable analysis for hemorrhagic stroke, hypertension (HR 2.28 95% CI 1.74-2.98) was highest risk factor. Multivariable analysis for all-cause mortality showed that congestive heart failure (HR 1.78 95% CI 1.65-1.92) and Eisenmenger syndrome (HR 2.91 95% CI 2.53-3.35) was highest risk factor. Conclusions: Korean ACHD patients have significantly higher incidence of co-morbidities including hypertension, diabetes mellitus, several heart diseases. They have a higher tendency of ischemic, hemorrhagic stroke and mortality. These findings suggest that medical surveillance and risk factor management is sustainedly needed for ACHD patients to reduce stroke and mortality in the future.

Abstract Background The effect of diabetic retinopathy (DR) on the development of sight-threatening cataracts was assessed using the National Health Insurance Research Database of Taiwan. Methods Patients diagnosed with diabetes mellitus (DM) and DR were enrolled in the study group. Age- and sex-matched DM individuals without DR and patients without DM served as the DM control group and non-DM control group, respectively, both with 1:4 ratios. The outcome was set as the performance of cataract surgery. Cox proportional hazard regression was used to calculate the adjusted hazard ratio (aHR) of DR considering multiple factors underlying cataract formation. Results A total of 3297 DR patients, 13,188 DM control patients and 13,188 non-DM control subjects were enrolled. The study group included 919 events of sight-threatening cataracts (27.87%), the DM control group included 1108 events (8.40%), and the non-DM control group included 957 events (7.26%). A multivariable analysis indicated that the study group presented a higher aHR of cataract surgery (2.93, 95% CI: 2.60–3.30) and a higher cumulative probability of cataract surgery than both the DM control and non-DM control groups (both log rank P < 0.001). In addition, both the proliferative DR (3.90, 95% CI: 3.42–4.45) and nonproliferative DR (2.35, 95% CI: 2.08–2.65) subgroups showed a higher aHR of cataract surgery than the DM control group. Conclusion The presence of DR increases the risk of sight-threatening cataracts that warrant surgery, and the effect is prominent among patients with both proliferative DR and nonproliferative DR.

ObjectiveTo explore the association between serum retinoic acid (RA) level in patients with acute ischemic stroke (AIS) and mortality risk in the 6 months after admission.MethodsFrom January 2015 through December 2016, patients admitted to 3 stroke centers in China for first-ever AIS were screened. The primary endpoint was all-cause mortality or cardiovascular disease (CVD) mortality in the 6 months after admission. The significance of serum RA level, NIH Stroke Scale score, and established risk factors in predicting mortality were determined. The integrated discrimination improvement (IDI) and net reclassification improvement (NRI) statistics were applied in statistical analysis.ResultsOf the 1,530 patients enrolled, 325 died within 6 months of admission, with an all-cause mortality of 21.2% and CVD-related mortality of 13.1%. In multivariable analysis, RA levels were expressed as quartiles with the clinical variables. The results of the second to fourth quartiles (Q2–Q4) were compared with the first quartile (Q1); RA levels showed prognostic significance, with decreased all-cause and CVD mortality of 55% and 63%, respectively. After RA was added to the existing risk factors, all-cause mortality could be better reclassified, in association with only the NRI statistic (p = 0.005); CVD mortality could be better reclassified with significance, in association with both the IDI and NRI statistics (p < 0.01).ConclusionsLow circulating levels of RA were associated with increased risk of all-cause and CVD mortality in a cohort of patients with first-incidence AIS, indicating that RA level could be a predictor independent of established conventional risk factors.

Background Stroke is the second leading cause of death worldwide and is associated with several risk factors with variable risk factor distribution by population. We report the types and frequency of the associated factors of stroke in north Iran. Methods Consecutive patients with stroke were recruited from 2014 to 2015. The two groups of ischemic and hemorrhagic stroke were compared with respect to age, sex, the prevalence, and distribution of the risk factors. Results Among 230 patients (84.3% ischemic stroke) with mean age of 61.2 years, hypertension (73%), diabetes mellitus (53%), cardiovascular disease (51%), and dyslipidemia (47%) were the most frequent risk factors. Hypertension was significantly more prevalent in males compared with females (88% vs. 60%, OR = 4.91, 95% CI: 2.48–9.71). Hypertension, smoking, and opioid consumption were associated with hemorrhagic stroke. Dyslipidemia was significantly higher in ischemic stroke (OR = 2.65, 95% CI: 1.21–5.8). Overall, 84.3% of stroke occurred in patients aged >50 years (92.8% of women vs. 74.5% of the men, OR = 4.43, 95% CI: 1.93–10.16, p = 0.001). Conclusion Stroke was more prevalent in females; hypertension was more prevalent in males. In the age group less than 50 years old, stroke is more prevalent in men.

Despite recent advances, only two-third of all strokes can be attributed to known causal risk factors. Homocysteine (tHcy), a sulfur-containing amino acid, is now considered to be an important risk factor for vascular diseases, along with the established risk factors like hyperlipidemia, hypertension, diabetes mellitus, and smoking. Elevated homocysteine levels play a causal role in the pathogenesis of atherosclerosis, thromboembolism and vascular endothelial dysfunction with an increased incidence of ischemic stroke.  This study aimed to find out the association of hyperhomocysteinemia with ischemic stroke. A total of 100 subjects were included in this study, 50 were ischemic stroke patients enrolled as case, and 50 were normal healthy individuals enrolled as control. Serum homocysteine level was measured in both case and control groups. The comparison was made in both groups regarding other common risk factors like diabetes mellitus, hypertension, smoking, dyslipidemia, family history, etc.  Among 100 patients, 50 had ischemic stroke and 50 were healthy individuals. In this study, out of all patients, abnormal serum homocysteine level was found in 32% of cases and 12% of controls. The mean (±SD) serum homocysteine level was found 16.50±13.86 μmole/L in cases and 9.46±3.49 μmole /L in the control group. Significant (p<0.05) difference was found between the case and the control. The incidence of hyperhomocysteinemia is higher in ischemic stroke cases than that in age-sex-matched healthy controls. In our study, serum homocysteine was high in both younger age group patients (16.65±14.55 μmole/L vs. 9.52±3.19 μmole/L) and older age group patients (16.33±9.87 vs. 9.35±3.97 μmole/L,) in case and control group respectively. Significant (p<0.05) difference was found between the case and the control. Multiple logistic regression analysis showed that abnormal serum homocysteine is an independent risk factor of ischemic stroke. So we conclude that hyperhomocysteinemia is an important and independent risk factor for the development of ischemic stroke. Hypertension and smoking are important contributory to elevated serum homocysteine. TAJ 2021; 34: No-1: 33-39

114 Background: Surgery is the cornerstone of curative intent therapy for patients with ACA of the E/GEJ. Many patients (pts) with LRC disease are medically unsuitable for resection, and thus alternative treatment strategies are required. Definitive CRT is a standard of care for esophageal squamous cell carcinoma, but less is known regarding the outcomes for ACA of the E/GEJ. Methods: Through the Cleveland Clinic tumor registry, and under an IRB approved protocol, pts with LRC (clinical stage I-III, AJCC 7th) ACA of the E/GEJ treated with either dRT or dCRT between 7/04 and 12/14 were identified. Overall survival (OS) from the date of diagnosis was the primary endpoint. In univariate analysis, Cox proportional hazard analysis was used to identify risk factors for mortality. On multivariable analysis, stepwise Cox proportional hazard analysis with variable entry criterion p≤0.10 and variable retention criteria p≤0.05 was used to identify risk factors for mortality. Results: From 7/04 to 12/14, 155 pts received definitive non-operative treatment (103 dCRT, 52 dRT). Clinical stage I disease was present in 20 (13.2%); stage II in 40 (26.5%) and stage III in 91 (60.3%) of the pts. Pts who received dCRT were younger (67 v 74 years, p<0.001) and had more advanced clinical stage (p=0.026). Loco-regional recurrence / persistence was the predominant form of treatment failure occurring in 60% of pts (dCRT 54.3%, dRT 71.2%, p=0.044). With a median follow-up of 34.9 months (range 2.0-107.1), the median OS was 17.3 months (15.6m dCRT, 19.8m dRT, p=0.40) and the projected 5 year OS was 11.5% (16.1% dCRT, 4.0% dRT, p = 0.030). On univariable and multivariable analysis, a worse ECOG performance status, increasing clinical T descriptor, and increasing clinical N descriptor were prognostic for a worse OS. After adjusting for these variables, dRT was associated with a worse OS [dRT/dCRT HR 1.79 (1.20-2.68) p=0.005]. Conclusions: Definitive RT/CRT for LRC ACA of the E/GEJ is associated with poor OS. Long-term survival is nonetheless possible in a small number of pts and appears more likely after dCRT.

Background and Purpose: Mitochondrial dysfunction is associated with increased Reactive Oxygen Species that are thought to drive risk of disease, including stroke. We investigated the association between mtDNA abundance, as a proxy for mitochondrial function, and incident stroke using multivariable-adjusted survival and Mendelian Randomization (MR) analyses. Methods: Cox-proportional hazard model analyses were conducted to assess the association between lymphocyte mtDNA abundance, and incident ischemic and hemorrhagic stroke over a maximum of 14-years follow-up in unrelated European-ancestry participants from UK Biobank. MR was conducted using independent (R2<0.001) lead variants for lymphocyte mtDNA abundance (p < 5x10-8) as instrumental variables. Single-Nucleotide Polymorphism (SNP)-ischemic stroke associations were derived from three published open source European-ancestry results databases (cases/controls): MEGASTROKE (60,341/454,450), UK Biobank (2,404/368,771) and FinnGen (10,551/202,223). MR was performed per study, and results were subsequently meta-analyzed. Results: A total of 288,572 unrelated participants (46% men) with mean (SD) age of 57 (8) years were included in the cox-proportional hazard analyses. After correction for considered confounders (BMI, hypertension, cholesterol, T2D), no association was found between mtDNA abundance and ischemic or hemorrhagic stroke (lowest 20% versus highest 20%: ischemic stroke, hazard ratio, 1.06 [95% confidence interval 0.95, 1.18]; hemorrhagic stroke, hazard ratio 0.97 [95% confidence interval, 0.82, 1.15]). In line, in the MR analyses, we found no evidence for an association between genetically-influenced mtDNA abundance and ischemic stroke (odds ratio, 1.04; confidence interval, 0.95, 1.15).

Clinical Fractures

Background:Patients with rheumatoid arthritis (RA) who have sarcopenia and stiff or painful joints might be at increased risk of falls and fractures.Objectives:The present study aimed to prospectively identify the incidence of clinical fractures and associated risk factors in patients with RA in a cohort study named the TOMORROW (UMIN000003876) that started in 2010.Methods:We evaluated anthropometric parameters, bone mineral density (BMD), disease activity, RA medication at baseline and observed the incidence of clinical fractures during nine years in 202 patients with RA (mean age, 58.6 y; medication with biological agents, 54.9%) and 202 age- and sex-matched non-RA volunteers (mean age, 57.4 y). We compared the incidence of clinical fractures between patients with RA and controls for nine years, and analyzed the risk factors for fractures using Cox proportional hazard model.Results:The incidence of clinical fractures in RA patients was significantly higher compared to controls (27.5 vs 18.3%, p=0.04). However, Cox proportional hazard model, adjusted by age, sex, smoking and body mass index, revealed that low BMD at thoracic vertebrae (< 0.7 g/cm2) significantly associated to the incidence of clinical fractures (hazard ratio [HR], 1.86, p=0.02), but not RA morbidity (HR 1.47, p=0.10) (Table 1). Among patients with RA, low BMD at the thoracic vertebrae (< 0.7 g/cm2) was the most prominent risk factor for clinical fractures (HR, 2.66, p=0.02) (Table 1). Although the use of glucocorticoid (GC) at baseline (HR, 1.68, p=0.09) was not a significant risk factor for fractures, a mean GC dose (≥ 2 mg/day) at entry increased risk for clinical fractures in the patients (HR, 1.91, p=0.04) (Table 1).Conclusion:RA per se was not a risk factor for clinical fractures in this cohort. Low BMD at the thoracic vertebrae and the use of GC with even low dose at entry were apparently significant risk factors for the incidence of clinical fractures among patients with RA.Disclosure of Interests:Kenji Mamoto: None declared, Tatsuya Koike Grant/research support from: Takeda Pharmaceutical, Mitsubishi Tanabe Pharma Corporation,Chugai Pharmaceutical, Eisai, Abbott Japan, Teijin Pharma, Banyu Pharmaceutical and Ono Pharmaceutical, Yutaro Yamada: None declared, Tadashi Okano: None declared, Yuko Sugioka: None declared, Masahiro Tada: None declared, Kentaro Inui Speakers bureau: Daiichi Sankyo Co.

SummaryProlactin and leptin are newly recognised platelet co-stimulators due to potentiation of ADP-induced platelet aggregation. Elevated leptin levels have recently been found to be a risk factor for ischemic stroke in both men and women, and especially in combination with increased blood pressure for hemorrhagic stroke in men. Until now an association between hyperprolactinemia and ischemic stroke has not been investigated systematically.We determined plasma prolactin and leptin levels as well as platelet P-selectin expression in 36 patients with ischemic stroke or transient ischemic attack and detecteda significant correlation between increased prolactin values and enhanced ADP stimulated P-selectin expression on platelets. In contrast, no correlation of leptin values with platelet P-selectin expression was found. Next we determined plasma prolactin and leptin as well as acquired and congenital risk factors of thrombophilia in patients with first-ever non-hemorrhagic stroke with or without atrial fibrillation. Excluding patients with such preexisting risk factors,21 patients with and 59 patients without atrial fibrillation were identified. Patients without atrial fibrillation revealed significantly higher plasma prolactin levels than patients with atrial fibrillation. Furthermore, the influence of aspirin or clopidogrel on prolactin stimulated P-selectin expression in vitro was tested, showing that aspirin was without effect,whereas clopidogrel significantly inhibited platelet P-selectin expression. In conclusion, hyperprolactinemia might be a novel risk factor for stroke mediating its thrombogenic effect through enhanced platelet reactivity, and this might correspond to a higher efficacy of antiplatelet combination therapy with clopidogrel compared to aspirin therapy alone.
