Abstract Background Metabolic abnormalities and body mass index (BMI) are known as apparent risk factors of recurrent stroke, but which one is more likely related to recurrent stroke remains uncertain. This study aimed to compare the metabolic phenotypes and BMI as indicators of recurrent stroke in Chinese hospitalized stroke patients. Methods In this retrospective population-based study, 856 hospitalized stroke patients from the Third Affiliated Hospital of Soochow University were enrolled. Recurrent stroke was defined as newly-onset stroke patients with a history of previous stroke. Metabolic phenotypes were categorized based on Adult Treatment Panel III criteria. BMI ≥ 25kg/m2 was defined as obesity. Results Among the hospitalized stroke patients, the prevalence of recurrent stroke was 21.9%. Metabolic abnormalities rather than BMI were significantly associated with recurrent stroke. Compared with metabolically healthy patients, metabolically unhealthy ones had 72% (odds ratio [OR] = 1.72, 95% confidence interval [CI] 1.01–2.68) increased risk of recurrent stroke, regardless of BMI and other confounding factors. Whereas, no statistical association between BMI and recurrent stroke were found. Metabolic status significantly improved risk prediction of recurrent stroke when adding to the conventional-risk-factor model (net reclassification index 17.6%, P = 0.0047; integrated discrimination improvement 0.7%, P = 0.014), while BMI did not. Conclusions Recurrent stroke is likely associated with metabolic abnormalities rather than with BMI. For the secondary prevention of stroke, controlling metabolic abnormalities is a more crucial method then BMI controlling in stroke patients.

Background: Cerebral microbleeds (CMBs) are radiographic markers of cerebral small vessel disease (CSVD) reported to independently predict recurrent stroke and mortality. However, characterization of CMBs in a large population of pure CSVD is lacking. We aimed to characterize CMBs in a well-defined population of lacunar stroke patients, and assess the relationship between CMBs and recurrent stroke and death. Methods: SPS3 was a randomized trial investigating optimal blood pressure target and antiplatelet regimen in 3020 patients with recent, symptomatic, MRI-confirmed lacunar stroke. CMBs were rated as per the Brain Observer MicroBleed Scale in all participants who had an interpretable axial T2*- GRE sequence available as part of their baseline MRI (n=1278, intra-rater reliability for + CMB 91% agreement, Kappa = 0.82). Results: CMBs were present in 30% of 1278 patients (mean age 63 y, 65% male, 75% history of hypertension). CMBs were lobar in 21%, deep in 44%, and mixed in 35% of cases. Of patients with CMBs, most (57%) had 1-2 CMBs, 31% had 3-10, and 12% >10. Male gender (OR 1.7, 95% CI 1.3-2.3), history of hypertension (1.6, 1.2-2.3), increased systolic blood pressure (1.2 per 20 mmHg, 1.1-1.4), non-diabetic (1.4, 1.1-1.9), multiple lacunar infarcts (1.9, 1.5-2.5) and moderate (1.7, 1.2-2.3) or severe (4.2, 3.0-5.9) white matter hyperintensities on MRI were independently associated with the odds of having CMBs in multivariable logistic regression. During a mean follow-up of 3.3 y, overall stroke recurrence was 2.5% per patient-y. In comparison to patients without CMBs, those with CMBs had a two-fold increased risk of stroke (HR 2.1, 1.4-3.1), after adjusting for assigned treatments and risk factors, whereas those with >10 CMBs had a four-fold increased risk (HR 4.0, 1.8-8.7). CMBs were not a risk factor for death (HR 1.2, 0.8-2.0). There were no interactions between CMBs and treatment assignments. Conclusions: In this largest reported cohort of lacunar stroke investigating CMBs, CMBs were highly prevalent and an independent predictor of stroke recurrence. Accordingly, patients with lacunar stroke and CMBs likely represent a more aggressive form of CSVD in need of efficacious therapeutic strategies. Further research is warranted in this field.

Abstract Background The neurodevelopmental and trauma theories are two widely cited models of psychosis. A third – the developmental risk factor model (DRFM) – recognises the combined role of neurodevelopmental risks and trauma. Our objective was to test these theories using preterm populations as a natural experiment, given the high prevalence of neurodevelopmental deficits and exposure to trauma. Methods Two population-based preterm birth cohorts, the Bavarian Longitudinal Study (BLS; N = 399) and EPICure Study (N = 184), were included with term-born controls. Peer victimisation in childhood was assessed by parent and child report and psychotic experiences (PE) were assessed in early adulthood. Different models of psychosis were tested using regression and mediation analyses. Results There was support for the trauma and DRFM in the BLS. Peer victimisation increased the risk of PE for preterm and term-born participants equally [odds ratio = 4.87, 95% confidence interval (CI) 1.96–12.08]. There was an indirect effect where preterm children were more likely to be victimised, which subsequently increased risk of PE [β = 1.12 (s.e. = 0.61), 95% CI 0.11–2.48]. The results were replicated in EPICure. Conclusions Exposure to trauma which is experienced more often by neurodevelopmental risk children rather than neurodevelopmental risk per se increases the risk of PE. The findings are consistent with the trauma model and DRFM. Interventions focused on reducing trauma may reduce the development of PE.

Abstract Aims Pulse pressure (PP) is a well-known risk factor for cardiovascular disease. However, the association between the PP and dementia is not well identified. This study aimed to determine the effect of PP on the risk of dementia development in different age subgroups using a longitudinal, population-based, and stroke-free cohort from the general population. Methods The association of PP with the development of incident dementia was assessed from January 1, 2005, to December 31, 2013, in 433,154 participants without a history of dementia or stroke from the Korea National Health Insurance Service-Health Screening cohort. The diagnosis of dementia was defined using the 10th revision of the International Classification of Disease codes. Results The mean age of the cohort was 55.7±9.2 years, 45.7% were women. Hypertension was 23.6%. The mean systolic and diastolic blood pressure of the entire cohort were 125.9±16.6 and 78.4±10.7 mmHg, respectively. Mean PP was 47.5±10.9 mmHg. In the middle-age group (40 to 50 year-old), increasing of 10 mmHg of PP was associated with incident dementia after adjusting mean blood pressure and clinical variables with a hazard ratio (HR) of 1.21 (95% confidence interval [CI]: 1.19–1.23, p<0.001). The association was still significant even after censoring for stroke (HR: 1.16, 95% CI: 1.08–1.22, p<0.001). In the older population, elevation of PP was not associated with dementia development (HR: 0.98, 95% CI: 0.95–1.01, p=0.247) Conclusion PP was associated with increased risk of dementia only in middle-aged population beyond that of mean arterial pressure.

AbstractThe association between bullous pemphigoid (BP) and melanoma is yet to be investigated. We aimed to assess assess the bidirectional association between BP and melanoma and to delineate the epidemiological features of patients with both diagnoses. A population-based cohort study was performed comparing BP patients (n = 3924) with age-, sex- and ethnicity-matched control subjects (n = 19,280) with regard to incident cases of melanoma. A case–control design was additionally adopted to estimate the risk of BP in individuals with a preexisting diagnosis of melanoma. The prevalence of preexisting melanoma was higher in patients with BP than in control subjects (1.5% vs. 1.0%, respectively; P = 0.004). A history of melanoma confers a 50% increase in the risk of subsequent BP (OR 1.53; 95% CI 1.14–2.06). This risk was higher among males (OR 1.66; 95% CI 1.09–2.54) and individuals older than 80 years (OR 1.63; 95% CI 1.11–2.38), and persisted after adjustment for multiple putative confounders including PD-1/PDL-1 antagonists (adjusted OR 1.53; 95% CI 1.14–2.06). Conversely, the risk of melanoma among patients with BP was slightly elevated, but did not reach the level of statistical significance (adjusted HR 1.13; 95% CI 0.73–1.74). Patients with a dual diagnosis of BP and melanoma were older at the onset of BP and had lower body mass index. A history of melanoma is associated with a 50% increase in the incidence of subsequent BP. Physicians managing patients with both conditions should be aware of this association. Further research is warranted to reveal the underlying mechanism of these findings.

Background:Cohort studies using nationwide health registers have shown an increased risk for affective and anxiety disorders in people with ankylosing spondylitis (AS) and rheumatoid arthritis (RA) (1-3). Moreover, a nationwide cohort study demonstrated an increased risk for mental disorders in people with rheumatic diseases (4).Objectives:We aimed to investigate the risk for psychiatric hospitalization following a hospitalization for rheumatic disease.Methods:Using data from the Czech nationwide register of all-cause hospitalizations, we obtained 4 971 individuals hospitalized (index hospitalization) between 2004 and 2012 for rheumatic diseases - RA, spondyloarthritis (including AS, psoriatic arthritis and undifferentiated spondyloarthritis), systemic lupus erythematosus and systemic sclerodermia, with no history of psychiatric and rheuma-related hospitalization in the previous 10 years from the index hospitalization. On these individuals, we randomly matched (on age, gender and year of index hospitalization) controls that were hospitalized in the same time period for a non-rheumatic disease and have no history of psychiatric and rheumatic hospitalization in the last 10 years from their index hospitalization, in the ratio of 1:5. We employed conditional logistic regression for assessing the risk for psychiatric hospitalization in the subsequent 3 years from the index hospitalization. To strengthen our results, we repeated the matching step 100 times and run the analysis on each resulting dataset separately, and pooled the results. The findings are expressed as odds ratios (OR) with 95% confidence intervals (95% CI).Results:We identified an elevated risk for psychiatric (OR = 1.34, 95% CI = 1; 1.78) and for affective disorders (OR = 2.19, 95% CI = 1.17; 4.1) in people hospitalized for rheumatic diseases. We did not find a statistically significant association with organic, psychotic and anxiety disorders.Conclusion:There is an increased risk for experiencing a psychiatric disorder in the period of 3 years after a rheuma-related hospitalization.References:[1]Shen C-C, Hu L-Y, Yang AC, Kuo BI-T, Chiang Y-Y, Tsai S-J.

Introduction: The effects of blood pressure (BP) reduction on clinical outcomes among acute stroke patient remain uncertain. Hypothesis: We tested the effects of immediate BP reduction on death and major disability at 14 days or hospital discharge and 3-month follow-up in acute ischemic stroke patients with and without a previous history of hypertension or use of antihypertensive medications. Methods: The China Antihypertensive Trial in Acute Ischemic Stroke (CATIS) randomly assigned patients with ischemic stroke within 48 hours of onset and elevated systolic BP (SBP) to receive antihypertensive treatment (N=2,038) or to discontinue all antihypertensive medications (N=2,033) during hospitalization. Randomization was stratified by participating hospitals and use of antihypertensive medications. Study outcomes were assessed at 14 days or hospital discharge and 3-month post-treatment follow-up. The primary outcome was death and major disability (modified Rankin Scale score≥3), and secondary outcomes included recurrent stroke and vascular events. Results: Mean SBP was reduced 12.7% in the treatment group and 7.2% in the control group within 24 hours after randomization (P<0.001). Mean SBP was 137.3 mmHg in the treatment group and 146.5 in the control group at day 7 after randomization (P<0.001). At 14 days or hospital discharge, the primary and secondary outcomes were not significantly different between the treatment and control groups by subgroups. At the 3-month follow-up, recurrent stroke was significantly reduced in the antihypertensive treatment group among patients with a history of hypertension (odds ratio 0.43, 95% CI 0.24-0.75, P=0.003) and among patients with a history of use of antihypertensive medications (odds ratio 0.41, 95% CI 0.20-0.84, P=0.01). All-cause mortality (odds ratio 2.84, 95% CI 1.11-7.27, P=0.03) was increased among patients without a history of hypertension. Conclusion: Immediate BP reduction lowers recurrent stroke among acute ischemic stroke patients with a previous history of hypertension or use of antihypertensive medications at 3 months. On the other hand, BP reduction increases all-cause mortality among patients without a history of hypertension.

Background: Population-based studies have identified several clinical variables associated with an increased risk of developing cutaneous melanoma that include phenotype, amount of and response to sun exposure, and family history. However, these observations are of limited relevance to clinical practice as the risk associated with each factor is individually modest and the characteristics of these variables lack precision when applied to a particular individual. Objective: To review the literature regarding recent advances made in the understanding of the genes and genetics of clinical variables associated with an increased risk of melanoma. Conclusion: Variants of the MC1R (melanocortin-1 receptor) have been identified as major determinants of high-risk phenotypes, such as red hair and pale skin, and the ability to tan in response to UV exposure. Several studies also suggest that such variants may increase melanoma risk independent of their contribution to phenotype. A strong genetic basis for both nevus density and size has been demonstrated and the link between nevi and the development of MM has become better defined. Finally, germline defects in several genes involved in cell cycle regulation, namely, p16 and CDK4, have been demonstrated in many familial melanoma kindreds. This progress has introduced the prospect of genetic testing as a means of identifying a limited number of high-risk individuals who can be targeted with regular screening and education regarding UV exposure and skin self-examination. Ultimately, through rational genetic therapy targeted to correcting the underlying molecular defect, altering the natural history of melanoma development may be possible.

Introduction: Herpes zoster (HZ) is associated with increased risk of stroke, and Zoster Vaccine Live (ZVL) reduces risk of HZ. No study examined the association between ZVL and risk for stroke. The present study examined this association among US older population. Methods: We included 1,382,051 Medicare fee-for-service beneficiaries age ≥66 years without a history of stroke and who received ZVL during 2008-2014, and 1,382,051 matched controls (using a comprehensive list of matching variables) without ZVL followed from ZVL receipt to December 31 2016. We used Cox proportional hazard models to examine the association between ZVL and composite fatal/non-fatal incident stroke outcomes. Results: During a median of 3.9 years follow-up (interquartile range 2.7-5.4), we documented 42,267 stroke events including 33,510 acute ischemic strokes (AIS) and 4,318 hemorrhagic strokes among beneficiaries who received ZVL over 5,890,113 person years. The corresponding numbers for controls were 48,139, 39,334, and 4,713 during 5,693,943 person years. Crude incidence comparing beneficiaries with and without ZVL were 7.18 vs. 8.45 per 1000 person years for all stroke, 5.40 vs. 6.53 for AIS, and 0.73 vs. 0.82 for hemorrhagic stroke (p<0.001 for difference). Adjusted hazard ratios comparing beneficiaries with ZVL to controls were 0.84 (95% CI 0.83-0.85), 0.82 (0.81-0.83), and 0.88 (0.84-0.91) for all stroke, AIS and hemorrhagic stroke respectively. The association between ZVL and risk for stroke appeared to be stronger among beneficiaries 66-79 years compared to those ≥80 years of age (p=0.020 for interaction), but largely consistent across sex, and racial groups. Conclusion: Among Medicare beneficiaries, receipt of ZVL was associated with lower incidence of stroke. Further study is needed to confirm our findings.
