OBJECTIVES Evaluation of the laryngeal adductor reflex (LAR) entails delivering air through an endoscope positioned 1 to 2 mm from the arytenoid mucosa to elicit bilateral vocal fold (VF) closure. This short working distance limits visualization to only the ipsilateral arytenoid and results in quantification of a single LAR metric: threshold pressure that evokes the LAR. Our goal was to evolve ...

We sought to develop individual-level Early Warning Indicators (EWI) of virologic failure (VF) for clinicians to use during routine care complementing WHO population-level EWI. A case-control study was conducted at a Durban clinic. Patients after ≥ 5 months of first-line antiretroviral therapy (ART) were defined as cases if they had VF [HIV-1 viral load (VL)>1000 copies/mL] and controls (2:1) i...

Sudden cardiac arrest is most often due to ventricular fibrillation (VF). When no cause found during diagnostic follow-up, classified as idiopathic VF. We hypothesize that subtle repolarization abnormalities may predispose VF, but cannot be detected from the 12-lead electrocardiogram (ECG). To study presence of time (RT) gradients in patients with VF using ECG and noninvasive electrocardiograph...

Purpose Therapeutic prostate-specific antigen (PSA) –targeted poxviral vaccines for prostate cancer have been well tolerated. PROSTVAC-VF treatment was evaluated for safety and for prolongation of progression-free survival (PFS) and overall survival (OS) in a randomized, controlled, and blinded phase II study. Patients and Methods In total, 125 patients were randomly assigned in a multicenter t...

BACKGROUND IEtravirine (ETR) was approved in France in Sept 2008, to be used in combination with a ritonavir-boosted protease inhibitor (bPI) and others antiretrovirals (ARV) in HIV-infected pre-treated patients. OBJECTIVES To describe in a real life setting efficacy and tolerability of ETR-including regimen and factors associated with virologic response. METHOD In the French DatAIDS cohort...

The elution order of 209 polychlorinated biphenyls (PCBs) was determined using five types commercially available capillary columns (VF-Xms, Rtx-20, VF-35ms, VF-1301ms and VF-200ms). In addition, the interference among molecular ion peaks PCDDs non-dioxin like PCB congeners, which affect during dioxin analysis by GC/MS, clarified.

PURPOSE To investigate the utility of the Corneal Visualization Scheimpflug Technology instrument (CST) to assess the progression of visual field (VF) damage in primary open angle glaucoma patients. METHOD A total of 75 eyes from 111 patients with primary open-angle glaucoma were investigated. All patients underwent at least nine VF measurements with the Humphrey Field Analyzer, CST measureme...

PURPOSE The degree of radiation-induced lung fibrosis (RILF) can be measured quantitatively by fibrosis volume (VF) on chest computed tomography (CT) scan. The purpose of this study was to investigate the interobserver and intraobserver variability in CT-based measurement of VF. MATERIALS AND METHODS We selected 10 non-small cell lung cancer patients developed with RILF after postoperative ra...

Dual-energy X-ray absorptiometry (DXA) is the gold standard method for measurement of bone mineral density (BMD). The aims of the current study are to compare the ability of BMD measurements to identify subjects with vertebral fractures (VF), when the lumbar spine (LS), hip or both sites are measured. 460 subjects aged 73+/-5.2 years participated in the study. Thoraco-lumbar spine radiographs w...
