The relationship between systolic pulmonary arterial pressure and Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios in patients with newly diagnosed chronic obstructive pulmonary disease.

Ann Noninvasive Electrocardiol 2020 05 11;25(3):e12691. Epub 2019 Sep 11.

Department of Chest Disease, Sincan State Hospital, Ankara, Turkey.

Introduction: The risk of sudden cardiac death (SCD) and arrhythmias has been shown to be common in chronic obstructive pulmonary disease (COPD) subjects. We aimed to evaluate the markers of arrhythmia such as QT, QTc (corrected QT), Tp-e, and cTp-e (corrected Tp-e) intervals, Tp-e/QT ratio, and Tp-e/QTc ratio in newly diagnosed COPD subjects in both right and left precordial leads.

Materials And Methods: The study group consisted of 74 subjects with obstructive respiratory function tests (RFTs). Read More

Hypoattenuation on CTA images with large vessel occlusion: timing affects conspicuity.

Neuroradiology 2017 May 31;59(5):471-475. Epub 2017 Mar 31.

Ottawa Hospital Research Institute, Ottawa, ON, Canada.

Purpose: Parenchymal hypoattenuation distal to occlusions on CTA source images (CTASI) is perceived because of the differences in tissue contrast compared to normally perfused tissue. This difference in conspicuity can be measured objectively. We evaluated the effect of contrast timing on the conspicuity of ischemic areas. Read More

Determination of the Association Between T2-weighted MRI and Gleason Sub-pattern: A Proof of Principle Study.

Acad Radiol 2016 11 14;23(11):1412-1421. Epub 2016 Sep 14.

Departments of Medical Biophysics and Oncology, Biomedical Engineering Graduate Program, University of Western Ontario, Lawson Health Research Institute, London Regional Cancer Program, London, Ontario, Canada.

Rationale And Objectives: The study aimed to determine the relationship between T2-weighted magnetic resonance imaging (MRI) signal and histologic sub-patterns in prostate cancer areas with different Gleason grades.

Materials And Methods: MR images of prostates (nā€‰=ā€‰25) were obtained prior to radical prostatectomy. These were processed as whole-mount specimens with tumors and the peripheral zone was annotated digitally by two pathologists. Read More

Cerebral Blood Volume ASPECTS Is the Best Predictor of Clinical Outcome in Acute Ischemic Stroke: A Retrospective, Combined Semi-Quantitative and Quantitative Assessment.

PLoS One 2016 29;11(1):e0147910. Epub 2016 Jan 29.

Neuroradiology Unit, Department of Neuroscience and Rehabilitation, Azienda Ospedaliera Universitaria, Ferrara, Italy.

Introduction: The capability of CT perfusion (CTP) Alberta Stroke Program Early CT Score (ASPECTS) to predict outcome and identify ischemia severity in acute ischemic stroke (AIS) patients is still questioned.

Methods: 62 patients with AIS were imaged within 8 hours of symptom onset by non-contrast CT, CT angiography and CTP scans at admission and 24 hours. CTP ASPECTS was calculated on the affected hemisphere using cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) maps by subtracting 1 point for any abnormalities visually detected or measured within multiple cortical circular regions of interest according to previously established thresholds.

Effects of entecavir and lamivudine for hepatitis B decompensated cirrhosis: meta-analysis.

World J Gastroenterol 2013 Oct;19(39):6665-78

Xiao-Guang Ye, Qi-Min Su, Department of Infectious Diseases, the Second Affiliated Hospital of Guangzhou Medical University, Guangzhou 510260, Guangdong Province, China.

Aim: To compare the effects of entecavir (ETV) and lamivudine (LAM) for the treatment of hepatitis B decompensated cirrhosis using a meta-analysis.

Methods: We conducted a literature search for all eligible studies published prior to May 30, 2013 using PUBMED, MEDLINE, EMBASE, the China National Knowledge Infrastructure (CNKI), the VIP database, the Wanfang database and the Cochrane Controlled Trial Register. Randomized controlled trials (RCTs) comparing ETV with LAM for the treatment of hepatitis B decompensated cirrhosis were included. Read More

Efficacy of lamivudine combined with adefovir dipivoxil versus entecavir monotherapy in patients with hepatitis B-associated decompensated cirrhosis: A meta-analysis.

J Clin Pharmacol 2014 Feb 4;54(2):189-200. Epub 2013 Oct 4.

Department of Infectious Diseases, Institute for Viral Hepatitis, Key Laboratory of Molecular Biology for Infectious Diseases, Ministry of Education, Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.

Whether the combination of lamivudine (LAM) plus adefovir (ADV) de novo is more effective than entecavir (ETV) monotherapy in patients with HBV-associated decompensated cirrhosis is still controversial. We searched seven randomized controlled trials that included 411 patients in this meta-analysis. There are 205 and 206 patients in these two groups separately. Read More

Abnormal metabolic brain networks in a nonhuman primate model of parkinsonism.

J Cereb Blood Flow Metab 2012 Apr 30;32(4):633-42. Epub 2011 Nov 30.

Center for Neurosciences, The Feinstein Institute for Medical Research, Manhasset, New York 11030, USA.

Parkinson's disease (PD) is associated with a characteristic regional metabolic covariance pattern that is modulated by treatment. To determine whether a homologous metabolic pattern is also present in nonhuman primate models of parkinsonism, 11 adult macaque monkeys with parkinsonism secondary to chronic systemic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and 12 age-matched healthy animals were scanned with [(18)F]fluorodeoxyglucose (FDG) positron emission tomography (PET). A subgroup comprising five parkinsonian and six control animals was used to identify a parkinsonism-related pattern (PRP). Read More
