The prevalence of cognitive impairment in laryngology treatment–seeking patients
Objectives/Hypothesis The incidence of cognitive impairment (CI) in the elderly general population is 10% to 20%. The incidence of CI in the elderly laryngology treatment–seeking population is unknown, and CI may impact decision making for elective medical/surgical treatment and negatively impact the outcome of voice/swallowing therapy. We sought to determine the prevalence of CI in elderly patients who are seeking laryngology care and to evaluate the feasibility of administering a cognitive screening...

Direct‐To‐Consumer Advertising of Over‐the‐Counter Sinonasal Remedies: A History of Mixed Messages
Sinus, cold, and allergy remedies comprise the most widely used sector of the over‐the‐counter (OTC) drug market. Direct‐to‐consumer advertising (DTCA) of pharmaceutical products has increased over the past 30 years, including the promotion of OTC drugs. The influence of DTCA on OTC sinonasal remedies comprises several positive and negative effects. Favorable aspects of this influence include empowerment and promotion of autonomy among patients, avoidance of low‐value clinical encounters, self‐directed...

Successful intravenous thrombolysis for ischemic stroke as a complication of coronary intervention in patients with ticagrelor pretreatment
Ticagrelor is an antiplatelet agent used for treatment of coronary artery disease [1] and it reversibly inhibits platelet function via P2Y12 receptor [2]. There is limited literature on intravenous thrombolysis for ischemic stroke in patients taking ticagrelor. Two cases of symptomatic intracranial hemorrhage and one case of retropharyngeal hematoma have been reported [2,3]. It is likely that more patients taking ticagrelor will present with acute ischemic stroke who may otherwise be eligible for...

Letter of Editor: Could variceal screening stratified by liver/spleen stiffness replace the role of endoscopy? – authors' reply
Abstract We would like to express our gratitude to Dr Lo for his insightful comments on our study.1 We fully acknowledge the role of endoscopic examinations in addition to variceal screening, such as to detect other upper gastrointestinal pathologies (e.g. peptic ulcer, portal hypertensive gastrolatry etc).2 Hence upper endoscopy should be offered to any cirrhotic patients who have clinical features of these pathologies, namely epigastric pain, anaemia, melaena or per rectal bleeding.

Glomerular filtration Rate Assessment In Liver disease (GRAIL): are we there yet?
Abstract Renal dysfunction is common in liver cirrhosis and it is associated with poor prognosis. However, we still have major limitations when assessing renal function in cirrhotic patients. Current available methods are biased and have a tendency to consistently overestimate glomerular filtration rates (GFR).

RNA Interference Therapy with ARC‐520 Results in Prolonged HBsAg Response in Patients with Chronic Hepatitis B Infection
Abstract ARC‐520, the first RNA interference (RNAi) therapeutic was designed to reduce all RNA transcripts derived from cccDNA, leading to a reduction in viral antigens and HBV DNA. We aimed to evaluate the depth of hepatitis B surface antigen (HBsAg) decline in response to multiple doses of ARC‐520 compared to placebo (PBO) in two randomized, multi‐center studies in nucleoside/nucleotide (NUC) experienced patients with hepatitis B e antigen negative (E‐neg) or positive (E‐pos) disease. A total...

Evaluation of algorithms for correction of transcranial magnetic stimulation-induced artifacts in electroencephalograms
Abstract Transcranial magnetic stimulation combined with electroencephalography (TMS-EEG) is widely used to study the reactivity and connectivity of brain regions for clinical or research purposes. The electromagnetic pulse of the TMS device generates at the instant of administration an artifact of large amplitude and a duration up to tens of milliseconds that overlaps with brain activity. Methods for TMS artifact correction have been developed to remove the artifact and recover...

Robust association between vascular habitats and patient prognosis in glioblastoma: An international multicenter study
Background Glioblastoma (GBM) is the most aggressive primary brain tumor, characterized by a heterogeneous and abnormal vascularity. Subtypes of vascular habitats within the tumor and edema can be distinguished: high angiogenic tumor (HAT), low angiogenic tumor (LAT), infiltrated peripheral edema (IPE), and vasogenic peripheral edema (VPE). Purpose To validate the association between hemodynamic markers from vascular habitats and overall survival (OS) in glioblastoma patients, considering...

Valvular imaging in the era of feature‐tracking: A slice‐following cardiac MR sequence to measure mitral flow
Background In mitral valve dysfunction, noninvasive measurement of transmitral blood flow is an important clinical examination. Flow imaging of the mitral valve, however, is challenging, since it moves in and out of the image plane during the cardiac cycle. Purpose To more accurately measure mitral flow, a slice‐following MRI phase contrast sequence is proposed. This study aimed to implement such a sequence, validate its slice‐following functionality in a phantom and healthy subjects, and...

Assessment of the potential therapeutic effects of omeprazole in Schistosoma mansoni infected mice
Abstract Schistosomiasis is a neglected chronic parasitic disease with a significant lasting morbidity. Currently, praziquantel (PZQ) is the most efficient drug for schistosomiasis worldwide. However, the possibility of the occurrence of resistance to PZQ is increasing. Therefore, there is a vital need to find new antischistosomal drugs or to increase the efficacy of the existing ones. Omeprazole is a proton pump inhibitor which is reported to have antiparasitic properties. Thus,...

Nrf2 dysfunction and impaired cellular resilience to oxidative stressors in the aged vasculature: from increased cellular senescence to the pathogenesis of age-related vascular diseases
Abstract Aging is associated with increased oxidative stress in vascular endothelial and smooth muscle cells, which contribute to the development of a wide range of diseases affecting the circulatory system in older adults. There is growing evidence that in addition to increased production of reactive oxygen species (ROS), aging critically impairs pathways determining cellular resilience to oxidative stressors. In young organisms, the evolutionarily conserved nuclear factor-erythroid-2-related...
