Impact of residual coronary lesions on outcomes of myocardial infarction patients with multi-vessel disease.

BACKGROUND: The residual burden of coronary artery disease (CAD) after percutaneous coronary intervention (PCI) drew a growing interest. The residual SYNTAX Score (rSS) was a strong prognostic factor of adverse events and all-cause mortality in patients who underwent PCI. In addition, the SYNTAX Revascularization Index (SRI), a derivative of rSS, was used to figure out the treated proportion of CAD and could be used as a prognostic utility in PCI for patients with multi-vessel disease (MVD). PURPOSE: We aimed at the assessment of the use of rSS and the SRI as predictors of in-hospital outcomes and up to two-year cumulative follow-up outcomes in patients with MVD who had PCI for the treatment of ST-Elevation Myocardial Infarction (STEMI) or Non-STEMI (NSTEMI). METHODS: We recruited 149 patients who had either STEMI or NSTEMI while having MVD and received treatment with PCI. We divided them into tertiles based on their rSS and SRI values. We calculated baseline SYNTAX Score (bSS) and rSS using the latest version of the calculator on the internet, and we used both scores to calculate SRI. The study end-points were In-hospital composite Major Adverse Cardiovascular Events (MACE) and its components, in-hospital death, and follow-up cumulative MACE up to 2 years. RESULTS: Neither rSS nor SRI were significant predictors of in-hospital adverse events, while female sex, hypertension, and left ventricular ejection fraction were independent predictors of in-hospital MACE. At the two-year follow-up, Kaplan-Meyer analysis showed a significantly increased incidence of MACE within the third rSS tertile (rSS > 12) compared to other tertiles (log rank p = 0.03). At the same time, there was no significant difference between the three SRI tertiles. Unlike SRI, rSS was a significant predictor of cumulative MACE on univariate Cox regression (HR = 1.037, p < 0.001). On multivariate Cox regression, rSS was a significant independent predictor of two-year cumulative MACE (HR = 1.038, p = 0.0025) along with female sex, hypertension, and left ventricular ejection fraction. We also noted that all patients with complete revascularization survived well throughout the entire follow-up period. CONCLUSIONS: Neither rSS nor SRI could be good predictors of in-hospital MACE, while the rSS was a good predictor of MACE at two-year follow-up. Patients with rSS values > 12 had a significantly higher incidence of cumulative MACE after 2 years. The best prognosis was achieved with complete revascularization.

Clinico-Radiological Correlation in 26 Egyptian Children with Glutaric Acidemia Type 1.

BACKGROUND: Glutaric acidemia type 1 (GA1) is an inherited neurometabolic disease with significant morbidity. However, neuro-radiological correlation is not completely understood. OBJECTIVE: The study aimed to characterize the neuroimaging findings and their association with neurological phenotype in GA1 children. METHODS: Twenty-six Egyptian children (median age = 12 months) diagnosed with GA1 underwent clinical evaluation and brain magnetic resonance imaging (MRI). We objectively assessed the severity of neurological phenotype at the time of MRI using movement disorder (MD) and morbidity scores. Evaluation of brain MRI abnormalities followed a systematic and region-specific scoring approach. Brain MRI findings and scores were correlated with MD and morbidity scores, disease onset, and presence of seizures. RESULTS: Fifteen (57.7%) cases had insidious onset, eight (30.8%) manifested acute onset, whereas three (11.5%) were asymptomatic. Ten (38.5%) cases had seizures, five of which had no acute encephalopathic crisis. Putamen and caudate abnormalities (found in all acute onset, 93.3 and 73.3% of insidious onset, and one of three asymptomatic cases) were significantly related to MD (p = 0.007 and 0.013) and morbidity (p = 0.005 and 0.003) scores. Globus pallidus abnormalities (50% of acute onset, 46.7% of insidious onset, and one of three of asymptomatic cases) were significantly associated with morbidity score (p = 0.023). Other MRI brain abnormalities as well as gray and white matter score showed no significant association with neurological phenotype. Younger age at onset, acute onset, and seizures were significantly associated with worse neurological manifestations. CONCLUSION: Patients with GA1 manifest characteristic and region-specific brain MRI abnormalities, but only striatal affection appears to correlate with neurological phenotype.

Clinicoradiologic Correlation in 22 Egyptian Children With Megalencephalic Leukoencephalopathy With Subcortical Cysts.

Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare genetic form of cerebral white matter disease whose clinicoradiologic correlation has not been completely understood. In this study, we investigated the association between clinical and brain magnetic resonance imaging (MRI) features in 22 Egyptian children (median age 7 years) with MLC. Gross motor function was assessed using the Gross Motor Function Classification System, and evaluation of brain MRI followed a consistent scoring system. Each parameter of extensive cerebral white matter T2 hyperintensity, moderate-to-severe wide ventricle/enlarged subarachnoid space, and greater than 2 temporal subcortical cysts was significantly associated (P < .05) with worse Gross Motor Function Classification System score, language abnormality, and ataxia. Having >2 parietal subcortical cysts was significantly related to a worse Gross Motor Function Classification System score (P = .04). The current study indicates that patients with MLC manifest signification association between certain brain MRI abnormalities and neurologic features, but this should be confirmed in larger studies.

Resveratrol Supplementation in Patients with Non-Alcoholic Fatty Liver Disease: Systematic Review and Meta-analysis.

BACKGROUND: Resveratrol is a potential treatment option for management of non-alcoholic fatty liver disease (NAFLD) due to its anti-inflammatory, antioxidant properties, and calorie restriction-like effects. We aimed to synthesise evidence from published randomized clinical trials (RCTs) about the efficacy of resveratrol in the management of NAFLD. METHODS: A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central was conducted using relevant keywords. Records were screened for eligible studies and data were extracted and synthesized using Review Manager Version 5.3 for windows. Subgroup analysis and sensitivity analysis were conducted. RESULTS: Four RCTs (n=158 patients) were included in the final analysis. The overall effect estimates did not favor resveratrol group in terms of: serum ALT (MD -2.89, 95%CI [-15.66, 9.88], p=0.66), serum AST (MD -3.59, 95%CI [-13.82, 6.63], p=0.49), weight (MD -0.18, 95%CI [-0.92, 0.55], p=0.63), BMI (MD -0.10, 95 %CI [-0.43, 0.24], p=0.57), blood glucose level (MD -0.27, 95%CI [-0.55, 0.01], p=0.05), insulin level (MD -0.12, 95%CI [-0.69, 0.46], p=0.69), triglyceride level (MD 0.04, 95%CI [-0.45, 0.53], p=0.87), and LDL level (MD 0.21, 95%CI [-0.41, 0.83], p=0.51). Pooled studies were heterogeneous. CONCLUSION: Current evidence is insufficient to support the efficacy of resveratrol in the management of NAFLD. Resveratrol does not attenuate the degree of liver fibrosis or show a significant decrease in any of its parameters.
