PURPOSE: Walnut is known to have unique favorable fatty acids, phytochemicals, and other nutrient profiles. As a result, there has been growing interest in evaluation of its health benefit related to cardiovascular disease (CVD). Although inverse associations of nut consumption and risk factors of cardiovascular disease have been reported in many epidemiological studies and qualitative reviews, few meta-analysis studies have been reported. This meta-analysis was conducted in order to evaluate the effect of a walnut-enhanced diet on CVD risk factors. METHODS: We searched Pubmed, Cochrane, Science Direct, and KISS (Korean studies Information Service System) through July 2014. A random-effects meta-analysis was conducted on 17 trials reporting total cholesterol (TC), 14 trials reporting LDL cholesterol (LDL-C), 15 trials reporting HDL cholesterol (HDL-C), 17 trials reporting triglyceride (TG), and four trials reporting flow-mediated dilation (FMD). RESULTS: In meta-analysis, intake of a walnut-enhanced diet resulted in significantly lowered TC, LDL-C, and TG by -0.124 mmol/l (95% CI, -0.209, -0.039; p = 0.004), -0.085 mmol/lL (95% CI, -0.167, -0.004; p = l0.039), and -0.080 mmol/l (95% CI, -0.155, -0.004; p = 0.039), respectively. The overall pooled estimate of the effect on FMD was +1.313% (95% CI, 0.744, 1.882, p = 0.000). HDL-C was not affected by walnut intake. No statistical heterogeneity was observed for any analysis. Results of funnel plots and Egger's regression suggested a low likelihood of publication bias in all biomarkers (p > 0.05). CONCLUSION: Findings of this meta-analysis provide consistent evidence that walnut-enhanced diet intake reduces the CVD risk factors.

Journal of Laboratory Medicine and Quality Assurance 2024;46(2):96-102
Background:
Quantitative viral load tests are essential for diagnosing and monitoring the response to antiviral treatment for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus type 1 (HIV-1) infections. The Hologic Aptima Quant assay (Hologic Inc., USA) is a fully integrated and automated quantitative assay based on real-time transcription-mediated amplification technology using the Panthers system.In this study, we evaluated the performance of the Hologic Aptima Quant assay for measuring HBV, HCV, and HIV-1 viral load, and compared the results with those obtained with Abbott Alinity m system (Abbott Laboratories, USA).
Methods:
The reproducibility and linearity of the assay were evaluated in the present study. Additionally, the precision, analytical specificity, interference, and limit of detection (LOD) of each assay on the Panther system were evaluated. A comparative evaluation between the Hologic Aptima Quant assay and the Abbott Alinity m assay was conducted using clinical patient samples.
Results:
The results of the precision study demonstrated excellent total precision, with the coefficient of variation of precision being less than 5%. The linearity of the viral loads was excellent for all assays (correlation coefficient [R2 ] >0.99 for HBV, HCV, and HIV-1). Furthermore, the specificity of all assays was determined to be 100%. The LOD results were 10 IU/mL for HBV and HCV assays, and 20 copies/mL for HIV-1 assay, with 100% replicates being detected. Additionally, the viral load measured with the Hologic Aptima Quant assay was strongly correlated with that measured with Abbott Alinity m assay (R2 =0.94–0.97).
Conclusions
The Hologic Aptima Quant assay demonstrated excellent performance, with results being comparable to those obtained with the Abbott Alinity m assay for detecting HBV, HCV, and HIV-1 viral loads.

BACKGROUND: Dobutamine and amrinone, phosphodiesterase-III inhibitor, are known to have both inotropic and vasodilatory properties. We evaluated the effects of both drugs on systemic and pulmonary hemodynamics in patients with pulmonary hypertension (PH). METHODS: With Institutional Review Board approval, 45 patients whose mean pulmonary arterial pressure was greater than 30 mmHg were studied. After sternotomy under the steady state of anesthesia and controlled ventilation (30 mmHg < PaCO2 < 40 mmHg), patients recieved one of following drugs for 30minutes (min); dobutamine 5.0ug/kg/min (Group I), low dose amrinone (loading dose 1.0 mg/kg, followed by infusion 7.5 g/kg/min, Group II) or high dose amrinone (loading dose 2.0 mg/kg, followed by infusion 10 g/kg/min, Group III). Hemodynamic variables were measured at 10 min and 30 min after start of infusion. RESULTS: Dobutamine didn't decrease pulmonary arterial pressure (PAP) and cause no hemodynamic change while low and high dose amrinone reduced PAP and especcially decrease of PAP in low dose amrinone group was statistically significnat. High dose amrinone increased cardiac index (CI) and decreased both systemic vascular resistance index (SVRI) and central venous pressure (CVP) more significantly than control value. CONCLUSIONS: In patients with chronic right ventricular failure associated with PH, amrinone may decrease the PAP and improve cardiac performance more effectively than dobutamin does. Increment of dosage of amrinone may not result in significant reduction of PAP.

In 25 aortic regurgitation patients relationship between degree of aortic regurgitation graded by 2-D color Doppler echocardiography and diastolic fluttering of anterior mitral leaflet on M-mode echocardiography was evaluated. The results were that all 13 aortic regurgitation patients, not associated with mitral stenosis, showed diastolic fluttering of anterior mitral leaflet; but only 3 patients among 12 patients (25%), associated with mitral stenosis, had characteristic mitral fluttering. On the whole, regardless of associated mitral stenosis, the sensitivity was 64%. In severe aortic regurgitation (Grade 3, 4 group) 12/13 patients revealed diastolic fluttering of anterior mitral leaflet (sensitivity of 92%); in mild to moderate aortic regurgitation (Grade 1, 2 group), only 4/12 patients (sensitivity of 33%). In conclusion, 2-D color Doppler echocardiography is a very useful method for detection of aortic regurgitation without difficulty. And in aortic regurgitation, not associated with mitral stenosis, fine fluttering of anterior mitral leaflet is a very sensitive sign of existence of aortic regurgitation, though there may be some false positive findings in normal individuals.

PURPOSE: This meta-analysis aimed to evaluate the effect of cassia cinnamon (Cinnamomum. cassia and C. aromaticum) on the glycemic response with a focus on the preparation of dehydrated powder and water extract. METHODS: We searched Pubmed, Cochrane, EMBASE, Science Direct, and the Korean Studies Information Service System (KISS) through May 2017. In the meta-analysis for the preparation of powder, eight trials reporting fasting blood glucose (FBG), four trials reporting HbA1c, and three trials reporting the postprandial glycemic response were included. For the water extract, six trials reporting FBG and four trials reporting HbA1c were eligible for this study. A random-effects model was used to calculate the pooled effect size. RESULTS: Cassia cinnamon powder intake significantly lowered FBG by −1.55 mmol/L (95% CI, −2.45, −0.64; p = 0.001) and the AUC of postprandial blood glucose level by −51.8 mmol/L·min (95% CI, −85.5, −18.1; p = 0.003). There was a significant difference in FBG between water extract of cinnamon and placebo of −0.76 mmol/L (95% CI, −1.09, −0.43; p = 0.000). However, blood HbA1c level was not significantly altered by any preparation of cinnamon. No statistical heterogeneity was observed for any analysis except in the case of FBG for cinnamon powder. Results of funnel plots and Egger's regression suggest a low likelihood of publication bias in all biomarkers (p > 0.05). CONCLUSION: According to this meta-analysis, there was possible evidence to support a relationship between cassia cinnamon intake and fasting glucose in both preparation of powder and water extract. Furthermore, new evidence of the health benefits on postprandial glucose regulation of cinnamon powder was obtained.
