Purpose: Listening is the gateway to learning in the mainstream classroom; however, classrooms are noisy environments, making listening challenging. Therefore, speech-in-noise tests that realistically incorporate the complexity of the classroom listening environment are needed. The aim of this article was to review the speech stimuli, noise stimuli, presentation mode, and presentation levels of current classroom speech-in-noise tests to determine how representative they are of real-world classroom listening.

Purpose: To investigate potential reasons for the mismatch between laboratory/clinic-based sentence-in-noise performance and real-world listening abilities, we recently developed a corpus of natural, spontaneously spoken speech with three vocal effort levels (Everyday Conversational Sentences in Noise [ECO-SiN]). Here, we examined the feasibility of using the ECO-SiN corpus for adaptive speech-in-noise testing, which might be a desirable format in certain situations (e.g.

During conversations people coordinate simultaneous channels of verbal and nonverbal information to hear and be heard. But the presence of background noise levels such as those found in cafes and restaurants can be a barrier to conversational success. Here, we used speech and motion-tracking to reveal the reciprocal processes people use to communicate in noisy environments.

A man in his late 60s presented with intermittent abdominal pain, nausea, vomiting and approximately 40 pounds of weight loss over the course of a year, most concerning for chronic mesenteric ischaemia. Given a prior negative workup, a CT angiogram was performed and revealed a wide neck mid-superior mesenteric artery pseudoaneurysm (PSA). As PSAs are susceptible to thrombus formation and distal emboli, this incidental finding was considered a possible explanation for his intermittent symptoms and thus required treatment.

June 2023

An 83-year-old woman with heart failure due to atrial tachycardia with reduced left ventricular ejection fraction died after cardioversion. Holter monitoring showed a massive prolongation of the QT interval resulting in torsade de pointe tachycardia with lethal outcome. The only reason of the QT prolongation was impaired left ventricular (LV) function and atrial ectopy.

Purpose: To compare the diagnostic accuracy and adverse event rates of intravascular ultrasound (US)-guided transvenous biopsy (TVB) versus those of computed tomography (CT)-guided percutaneous needle biopsy (PNB) for retroperitoneal (RP) lymph nodes.

Materials And Methods: In this single-institution, retrospective study, 32 intravascular US-guided TVB procedures and a sample of 34 CT-guided PNB procedures for RP lymph nodes where targets were deemed amenable to intravascular US-guided TVB were analyzed. Procedural metrics, including diagnostic accuracy, defined as diagnostic of malignancy or a clinically verifiable benign result, and adverse event rates were compared.

Purpose: The purpose of this study was to prospectively evaluate the clinical and radiological results of double level osteotomy (distal femoral lateral closed wedge and proximal tibial medial open wedge) in medial osteoarthritis and varus malalignment due to bifocal deformity of femur and tibia.

Methods: From 2017 to 2019 all cases of DLO in osteoarthritic varus malaligned knees with bifocal deformity (femoral and tibial deformity) were prospectively enrolled into this observational therapeutic study. Evaluation was performed preoperatively, at six, twelve, 18 and 24 months with regard to survival (not requiring arthroplasty), functional outcome [subjective International Knee Documentation Committee score (IKDC), Oxford Knee Score (OKS), Knee Injury and Osteoarthritis Outcome score (KOOS) and Tegner Activity Scale], pain level (numeric rating scale), subjective satisfaction (rating 1-5), radiographic parameters on a pre-and postoperative full leg x-rays (mechanical axis, mechanical proximal tibial and distal femoral angles) and complications.

Purpose: This study aimed to develop and test a measure of real-time continuous speech understanding to be used with natural dialogues.

Method: The measure was based on a category monitoring paradigm and employed five existing recordings of natural dialogues from which the different test categories and associated target words were derived. For each dialogue, a listener was first given a semantic category and asked to press a button as quickly as possible whenever they heard an instance of the category.

Background: Depressive and obsessive-compulsive (OCD) symptoms often co-occur and a number of possible explanations for this co-occurrence have been explored, including shared biological and psychosocial risk factors. Network approaches have offered a novel hypothesis for the link between depression and OCD: functional inter-relationships across the symptoms of these conditions. The few network studies in this area have relied largely on item, rather than process-level constructs, and have not examined relationships dimensionally.

Laboratory and clinical-based assessments of speech intelligibility must evolve to better predict real-world speech intelligibility. One way of approaching this goal is to develop speech intelligibility tasks that are more representative of everyday speech communication outside the laboratory. Here, we evaluate speech intelligibility using both a standard sentence recall task based on clear, read speech (BKB sentences), and a sentence recall task consisting of spontaneously produced speech excised from conversations which took place in realistic background noises (ECO-SiN sentences).

This study investigated the effect of hearing loss on binaural unmasking (BU) for the intelligibility of speech in noise. Speech reception thresholds (SRTs) were measured with normal-hearing (NH) listeners and older mildly hearing-impaired (HI) listeners while varying the presentation level of the stimuli, reverberation, modulation of the noise masker, and spatial separation of the speech and noise sources. On average across conditions, the NH listeners benefited more (by 0.

Ecological momentary assessment (EMA) outcome measures can relate people's subjective auditory experience to their objective acoustical reality. While highly realistic, EMA data often contain considerable variability, such that it can be difficult to interpret the results with respect to differences in people's hearing ability. To address this challenge, a method for "guided" EMA is proposed and evaluated.
