Silent Brain Infarction

Silent brain infarction (SBI) has been considered as a subclinical risk factor for symptomatic possible future stroke. We investigated the association between serum inflammatory markers and SBI. Patients (n = 54) diagnosed with SBI as the study group and 52 individuals as the control group were included in this study. Silent brain infarction is defined as a hyperintense lesion that was ≥3 mm in 1 dimension on fluid-attenuated inversion recovery T2-weighted magnetic resonance image, if the patient had normal neurological examination or had an abnormality that was not consistent with the brain lesion locations, after being evaluated by a neurologist. Serum endocan levels ( P = .036) and high-sensitivity C-reactive protein (hsCRP; P = .022) were significantly higher in patients with SBI than the controls. Pentraxin 3, erythrocyte sedimentation rate, white blood count, lymphocyte, monocyte, neutrophil, low-density lipoprotein, and triglyceride levels were not significantly different when comparing the groups with and without SBI. There was a significant correlation ( r = −0.196; P = .16) between hsCRP and endocan levels in the SBI group. Endocan, a novel biomarker of endothelial pathology, was significantly increased in patients with SBI and may be useful to predict the future risk of stroke.

The aim of this study was to analyze the relationship between the qualitative abnormalities on nailfold videocapillaroscopy (NVC), and the concentrations of selected biomarkers (sE-selectin, endothelin-1, high-sensitivity c-reactive protein (hsCRP)) and lipid metabolism parameters in children and adolescents with Raynaud’s phenomenon (RP). Raynaud’s phenomenon, to assess whether nailfold capillary changes may reflect the degree of systemic blood vessel abnormalities. The study group included 66 patients (34 undifferentiated—uRP and 32 secondary—sRP) aged 6–19 years and the control group. In both groups, NVC was performed and the selected biomarkers were measured (sE-selectin, endothelin-1, hsCRP) and lipid profile. Endothelin-1, sE-selectin and hsCRP concentrations in patients from both RP groups were significantly higher; concentration of HDL fraction was significantly lower compared with the control group. The analysis of multiple linear regression demonstrated that megacapillaries most strongly determine the sE-selectin value (p = 0.04) and hsCRP (p = 0.03). Both the total cholesterol and low-density lipoprotein (LDL) fraction concentrations were determined by the presence of avascular areas (p = 0.02). In conclusion, specific pathologic NVC changes were associated with higher endothelial damage biomarkers concentration and adverse changes in the lipid profile.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.

Aims: To explore early intensive lipid-lowering therapy in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Background: Lowering low-density lipoprotein cholesterol (LDL-C) levels can reduce cardiovascular morbidity and mortality in patients with atherosclerotic cardiovascular disease. Due to many reasons, the need for early intensive lipid-lowering therapy is far from being met in Chinese NSTE-ACS patients at high-risk of recurrent ischaemic events. Objective: To evaluate the feasibility, safety and efficacy of starting evolocumab in hospital to lower LDL-C levels in Chinese patients with NSTE-ACS. Methods: In this prospective cohort study initiated by researchers, 334 consecutive patients with NSTE-ACS who had sub-standard LDL-C levels (LDL-C ≥2.3 mmol/L after regular oral statin treatment for at least 4 weeks; or LDL-C ≥3.2 mmol/L without regular oral statin treatment) were included. Patients who agreed to treatment with evolocumab (140 mg subcutaneously every 2 weeks, initiated in hospital and used for 12 weeks after discharge) were enrolled in the evolocumab group (n=96) and others in the control group (n=238). All enrolled patients received regular statin treatment (atorvastatin 20 mg/day or rosuvastatin 10 mg/day; doses unchanged throughout the study).The primary endpoint was the change in LDL-C levels from baseline to week 12. Results: Most patients (67.1%) had not received regular statin treatment before. In the evolocumab group, LDL-C levels decreased significantly at week 4 and remained stable at week 8 and 12 (all p<0.001). At week 12, the LDL-C percentage change from baseline in the evolocumab group was -79.2±12.7% (from an average of 3.7 to 0.7 mmol/L), while in the control group it was -37.4±15.4% (from an average of 3.3 to 2.0 mmol/L). The mean difference between these 2 groups was -41.8% (95% CI -45.0 to -38.5%; p<0.001). At week 12, the proportions of patients with LDL-C levels <1.8 mmol/L and 1.4 mmol/L in the evolocumab group were significantly higher than in the control group (96.8 vs 36.1%; 90.6 vs 7.1%; both p<0.001). The incidence of adverse events and cardiovascular events was similar in both groups. Conclusions: In this prospective cohort study we evaluated the early initiation of evolocumab in NSTE-ACS patients in China. Evolocumab combined with statins significantly lowered LDL-C levels and increased the probability of achieving recommended LDL-C levels, with satisfactory safety and well tolerance.

The non-traditional cardiovascular (CV) risk factors that appear to be of most clinical interest include: apolipoprotein A (ApoA), apolipoprotein B (ApoB), high-sensitivity C-Reactive protein (hsCRP), homocysteine, interleukin 1 (IL1), lipoprotein (a) [Lp(a)], the density of low-density lipoprotein (LDL) particles, the LDL particle number, tissue/tumor necrosis factor-α (TNF-α) and uric acid. These non-traditional risk factors may be of value in adding further confirmation and attention to suspected significant CV risk. They can also provide a better understanding of current concepts of atherogenesis (e.g. various potential mechanisms associated with inflammation) as an etiology and in guiding current plus future therapies. In the mid-20th century, atherosclerosis and CV disease were considered mechanistic occurrences with essentially no attention to possible metabolic and molecular etiologies. Therefore, the only treatments then centered around mainly surgical procedures to try to improve blood flow, first with peripheral arterial disease (PAD) and later coronary artery disease (CAD). Now, failure to treat CV risk factors, especially where there is good evidence-based medicine, as in the case of statins for high CV risk patients, is considered medical negligence. Nevertheless, many problems remain to be solved regarding atherosclerosis prevention and treatment.

Sedentary Life Style

In different epidemiological studies, an association between sedentary life style and incidence of cardiovascular diseases has been demonstrated. Dyslipidaemia is one of the important risk factors of cardiovascular disease. An association of dyslipidaemia with sedentary life style has been considered. This study was carried out among 50 sedentary workers (teachers, office staffs, bank employees) at Pabna District and 50 individuals with non-sedentary jobs matched for age group and sex for the control group to see the association. Body mass index (BMI), blood pressure (BP), plasma level of glucose, total cholesterol, low density lipoprotein (LDL), and triglycerides (Tgs) were found to be significantly higher whereas high density lipoprotein (HDL) was found to be significantly lower among the sedentary workers as compared with the control subjects. From the study, it appears that dyslipidaemia is more common in sedentary workers and the relative risk for cardiovascular disease is increased among them due to the sedentary nature of their jobs.

A New Technique

A new technique has been developed to identify low-density-lipoprotein (LDL) receptors on nitrocellulose membranes, after transfer from SDS/polyacrylamide gels, by ligand blotting with biotin-modified LDL. Modification with biotin hydrazide of periodate-oxidized lipoprotein sugar residues does not affect the ability of the lipoprotein to bind to the LDL receptor. Bound lipoprotein is detected with high sensitivity by a streptavidin-biotin-peroxidase complex, and thus this method eliminates the need for specific antibodies directed against the ligand. The density of the bands obtained is proportional to the amount of pure LDL receptor protein applied to the SDS/polyacrylamide gel, so that it is possible to quantify LDL receptor protein in cell extracts. Biotin can be attached to other lipoproteins, for example very-low-density lipoproteins with beta-mobility, and thus the method will be useful in the identification and isolation of other lipoprotein receptors.

Aim: To prove if a nutraceutical containing Ilex paraguariensis (Ilex L. spp. Aquifoliales) (an extract of the leaf standardized to 2% I-deoxinojirimcina), white mulberry (Morus spp., Moraceae), and chromium picolinate can be effective in improving glycemic status in subject with dysglycemia. Methods: We randomized patients to consume placebo or the nutraceutical, self-administered once a day, one tablet at breakfast, for 3 months. Results: A reduction in fasting plasma glucose, postprandial glucose, and glycated hemoglobin was observed with the nutraceutical combination, both compared to baseline and placebo. Data suggested a decrease in the Homeostasis Model Assessment index with the nutraceutical, both compared to baseline and placebo. The M value, an index of insulin sensitivity, obtained after nutraceutical treatment was higher compared to baseline. We recorded a decrease in total cholesterol, low-density lipoprotein-cholesterol, and triglycerides with the nutraceutical combination compared to baseline and placebo. A decrease in high-sensitivity C-reactive protein was observed with the nutraceutical combination compared to baseline and placebo. Conclusions: A nutraceutical containing Ilex paraguariensis, white mulberry, and chromium picolinate can be helpful in improving glycemic status and lipid profile in dysglycemic subjects.
