BackgroundCardiovascular disease (CVD) is the leading cause of mortality among subjects with type 2 diabetes (T2D), and diabetic retinopathy (DR) has been associated with an increased risk for CVD. The present study was designed to test the concept that T2D patients with DR, but without previous cardiovascular (CV) events and with normal renal function, have an increased atherosclerotic burden compared with patients without DR.MethodsA cross-sectional study was performed using patients with normal renal function (estimated glomerular filtration rate (eGFR) >60 ml/min) and without previous CV events. A total of 312 patients (men, 51%; mean age, 57 yrs; age range 40–75 yrs) were included in the study; 153 (49%) of the patients had DR. B-mode carotid ultrasound imaging was performed for all of the study subjects to measure the carotid intima-media thickness (cIMT) and carotid plaques in the common carotid artery (CCA), bifurcation and internal carotid artery (ICA).ResultsThe percentage of carotid plaques in T2D patients with DR was higher than in T2D patients without DR (68% vs. 52.2%, p = 0.0045), and patients with DR had a higher prevalence of ≥2 carotid plaques (44.4% vs. 21.4%; p < 0.0001). No differences were observed in the cIMT measured at different carotid regions between the patients with or without DR. Using multivariate logistic regression (adjustment for major risk factors for atherosclerosis), DR was independently associated with mean-internal cIMT (p = 0.0176), with the presence of carotid plaques (p = 0.0366) and with carotid plaque burden (≥2 plaques; p < 0.0001).ConclusionsThe present study shows that DR in T2D patients without CVD and with normal renal function is associated with a higher atherosclerotic burden (presence and number of plaques) in the carotid arteries. These patients may be at a higher risk for future CV events; therefore, an ultrasound examination of the carotid arteries should be considered in patients with DR for more careful and individualised CV assessment and follow-up.

Objective: To discover, by using metabolomics, novel candidate biomarkers for stroke recurrence (SR) with a higher prediction power than present ones.Methods: Metabolomic analysis was performed by liquid chromatography coupled to mass spectrometry in plasma samples from an initial cohort of 131 TIA patients recruited ,24 hours after the onset of symptoms. Pattern analysis and metabolomic profiling, performed by multivariate statistics, disclosed specific SR and large-artery atherosclerosis (LAA) biomarkers. The use of these methods in an independent cohort (162 subjects) confirmed the results obtained in the first cohort.Results: Metabolomics analyses could predict SR using pattern recognition methods. Low concentrations of a specific lysophosphatidylcholine (LysoPC[16:0]) were significantly associated with SR. Moreover, LysoPC(20:4) also arose as a potential SR biomarker, increasing the prediction power of age, blood pressure, clinical features, duration of symptoms, and diabetes scale (ABCD2) and LAA. Individuals who present early (,3 months) recurrence have a specific metabolomic pattern, differing from non-SR and late SR subjects. Finally, a potential LAA biomarker, LysoPC(22:6), was also described. Conclusions:The use of metabolomics in SR biomarker research improves the predictive power of conventional predictors such as ABCD2 and LAA. Moreover, pattern recognition methods allow us to discriminate not only SR patients but also early and late SR cases.

Naltrexone was well-tolerated, as the rate of adverse events was low, and safe, as it did not interfere with the normalization of biochemical markers of heavy drinking or alter liver function markers. Naltrexone seemed to reduce relapse rate to heavy drinking, but we found no differences in other alcohol consumption variables between naltrexone- and placebo-treated groups. Although the naltrexone group showed a tendency to consume fewer drinks per drinking day and had a longer time to first drink, differences were not statistically significant.

Five recent randomized controlled trials provided clear evidence that endovascular thrombectomy (EVT) improves outcomes after acute ischemic stroke caused by large vessel occlusions (LVOs), [1][2][3][4][5] and current guidelines recommend EVT in addition to intravenous thrombolysis (IVT) within 4.5 hours among patients with anterior circulation strokes and LVO. 6,7 Patients eligible for IVT should receive it without delay even if EVT is being considered, but the particular benefit of IVT is not yet well established. Moreover, in the real world, a significant proportion of acute ischemic stroke patients receive IVT at local stroke centers where EVT is not available. Such centers apply a drip and ship protocol when an EVT candidate is identified, with the necessary subsequent transfer causing a delayed puncture. In this context, building up evidence of the specific role of IVT when added to EVT among LVO patients is necessary to reorganize stroke systems of care accordingly. We compared direct EVT (dEVT) against combined IVT+EVT in patients with anterior circulation strokes caused by LVO. MethodsWe used data included in the SONIIA registry (Sistema Online d'Informació de l'Ictus Agut), a government-mandated, populationbased, externally audited, prospective database that includes all acute ischemic stroke patients treated with reperfusion therapies in the region Background and Purpose-Whether intravenous thrombolysis adds a further benefit when given before endovascular thrombectomy (EVT) is unknown. Furthermore, intravenous thrombolysis delays time to groin puncture, mainly among drip and ship patients. Methods-Using region-wide registry data, we selected cases that received direct EVT or combined intravenous thrombolysis+EVT for anterior circulation strokes between January 2011 and October 2015. Treatment effect was estimated by stratification on a propensity score. The average odds ratios for the association of treatment with good outcome and death at 3 months and symptomatic bleedings at 24 hours were calculated with the Mantel-Haenszel test statistic. Results-We included 599 direct EVT patients and 567 patients with combined treatment. Stratification through propensity score achieved balance of baseline characteristics across treatment groups. There was no association between treatment modality and good outcome (odds ratio, 0.97; 95% confidence interval, 0.74-1.27), death (odds ratio, 1.07; 95% confidence interval, 0.74-1.54), or symptomatic bleedings (odds ratio, 0.56; 95% confidence interval, 0.25-1.27). of Catalonia from January 2011. Further details of this registry have been published elsewhere. 8 Briefly, the database includes relevant baseline information (prestroke medical history, medications and functional status, time of stroke onset and hospital arrival, severity, time of neuro/ vascular imaging, IVT and groin puncture time, and complications) and the neurological situation at 24 to 36 hours post-treatment, including symptomatic bleedings. Outcome variables at 3 months are good outcome (modif...

according to our results, MRI, including DWI, should be considered a preferred diagnostic test when investigating patients with potential TIAs. The combination of neuroimaging and vascular information could improve prognostic accuracy in patients with TIA.

This study reinforces the role of revascularization and time to treatment to achieve enhanced functional outcomes and identifies other clinical features that independently predict good/fatal outcome after endovascular treatment/therapy.

OBJECTIVEWe sought to examine the presence and severity of brain small vessel disease (SVD) in patients with type 2 diabetes and diabetic retinopathy (DR) compared with those without DR. RESEARCH DESIGN AND METHODSWe evaluated 312 patients with type 2 diabetes without previous cardiovascular disease (men 51%; mean age 57 years; age range 40-75 years); 153 patients (49%) had DR. MRI was performed to evaluate the presence and severity (age-related white matter changes scale) of white matter lesions (WMLs) and lacunes, and transcranial Doppler ultrasound was used to measure the Gosling pulsatility index (PI) of the middle cerebral artery (MCA). RESULTSThe prevalence of lesions of cerebral SVD (WML and/or lacunes) was higher in patients with DR (40.2% vs. 30.1% without DR, P = 0.04). Age (P < 0.01) and systolic blood pressure (P = 0.02) were associated with the presence of SVD. The severity of SVD was associated with age and the presence of DR (P < 0.01 and P = 0.01, respectively). Patients with DR showed a higher MCA PI compared with those without DR (P < 0.01). Age, systolic and diastolic blood pressure, and retinopathy and its severity were associated with an increased MCA PI (P < 0.01 for all variables). A positive correlation was found between MCA PI values and the presence and severity of SVD (P < 0.01 for both variables). CONCLUSIONSPatients with type 2 diabetes who have DR have an increased burden of cerebral SVD compared with those without DR. Our findings suggest that the brain is a target organ for microangiopathy, similar to other classic target organs, like the retina.Patients with type 2 diabetes mellitus have an increased risk of cardiovascular (CV) morbidity and mortality. The chronic deleterious effects of hyperglycemia are classically separated into microvascular and macrovascular complications. In addition to the classic target organs of microangiopathy, such as the retina or the kidneys, the brain has also been described more recently as a target organ for diabetic microvascular complications (1).Cerebral small vessel disease (SVD) is the term commonly used to describe a syndrome of clinical, cognitive, neuroimaging, and neuropathological findings that

Abnormal ABI was associated with classical risk factors, especially hypertension. The measurement of ABI amongst patients with IS appeared to be useful to identify high-risk patients and plan adequate prevention therapies.
