Investigating the salient characteristics of clear speech that contribute to improved speech perception

Clear speech is one strategy used to promote successful communication strategy with people who have hearing loss. It occurs naturally and is more intelligible than speech used in conversational settings. However, the aspect of clear speech that makes it more intelligible than conversational speech is unknown. The aim of this study is to investigate the importance of clear speech formant contours. By hybridizing a conversational speech carrier sentence with a clear speech formant contour at a vowel-nasal transition in a target word, it will be determined whether clear speech formant contours impact the way normally hearing listeners understand an otherwise conversational speech sentence. A total of 30 normally hearing subjects between the ages of 18 and 32 participated in this study. Participants listened to 30 clear, conversational, and manipulated sentences presented in Sine Wave Speech and were asked to identify the last word in the sentences out of four multiple choice answers. Participants responses were scored for number correct out of 10 for each of the 3 conditions. The results indicated no difference in identification between the conditions. Formant contour as an isolated cue as presented in this study does not appear to differentiate clear and conversational speech

Efficacy of Tinnitus Retraining Therapy (TRT) in Adults with Bothersome Tinnitus

Tinnitus is the perception of sound in the absence of an external stimulus. Hearing ringing, roaring, or rushing in the ears or head is a common phenomenon in adults, affecting about 25% of the global population. For most people, tinnitus can be easily ignored. However, 1-7% of adults in the United States are are living with bothersome, and potentially debilitating tinnitus that causes a disruption of daily life impacting their mood, sleep, and mental health (Bauer et al, 2017). There are many different types of treatment options for people with tinnitus. Some treatment options include the use of sound maskers, Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Progressive Tinnitus Management (PTM), and Tinnitus Retraining Therapy (TRT). Using a systematic review, we are interested in analyzing the efficacy of TRT. TRT focuses on both conscious and subconscious connections to attempt to reduce the perception of tinnitus. The treatment consists of intensive counseling and the addition of sound therapy. The aim of this systematic review is to assess patient’s perceived benefits from TRT

BHPR research: qualitative1. Complex reasoning determines patients' perception of outcome following foot surgery in rheumatoid arhtritis

Background: Foot surgery is common in patients with RA but research into surgical outcomes is limited and conceptually flawed as current outcome measures lack face validity: to date no one has asked patients what is important to them. This study aimed to determine which factors are important to patients when evaluating the success of foot surgery in RA Methods: Semi structured interviews of RA patients who had undergone foot surgery were conducted and transcribed verbatim. Thematic analysis of interviews was conducted to explore issues that were important to patients. Results: 11 RA patients (9 ♂, mean age 59, dis dur = 22yrs, mean of 3 yrs post op) with mixed experiences of foot surgery were interviewed. Patients interpreted outcome in respect to a multitude of factors, frequently positive change in one aspect contrasted with negative opinions about another. Overall, four major themes emerged. Function: Functional ability & participation in valued activities were very important to patients. Walking ability was a key concern but patients interpreted levels of activity in light of other aspects of their disease, reflecting on change in functional ability more than overall level. Positive feelings of improved mobility were often moderated by negative self perception ("I mean, I still walk like a waddling duck”). Appearance: Appearance was important to almost all patients but perhaps the most complex theme of all. Physical appearance, foot shape, and footwear were closely interlinked, yet patients saw these as distinct separate concepts. Patients need to legitimize these feelings was clear and they frequently entered into a defensive repertoire ("it's not cosmetic surgery; it's something that's more important than that, you know?”). Clinician opinion: Surgeons' post operative evaluation of the procedure was very influential. The impact of this appraisal continued to affect patients' lasting impression irrespective of how the outcome compared to their initial goals ("when he'd done it ... he said that hasn't worked as good as he'd wanted to ... but the pain has gone”). Pain: Whilst pain was important to almost all patients, it appeared to be less important than the other themes. Pain was predominately raised when it influenced other themes, such as function; many still felt the need to legitimize their foot pain in order for health professionals to take it seriously ("in the end I went to my GP because it had happened a few times and I went to an orthopaedic surgeon who was quite dismissive of it, it was like what are you complaining about”). Conclusions: Patients interpret the outcome of foot surgery using a multitude of interrelated factors, particularly functional ability, appearance and surgeons' appraisal of the procedure. While pain was often noted, this appeared less important than other factors in the overall outcome of the surgery. Future research into foot surgery should incorporate the complexity of how patients determine their outcome Disclosure statement: All authors have declared no conflicts of interes

Cerebrospinal fluid total protein cannot reliably distinguish true subarachnoid haemorrhage from other causes of raised cerebrospinal fluid net bilirubin and net oxyhaemoglobin absorbances

Background In cerebrospinal fluid (CSF) spectrophotometry, if the net bilirubin absorbance (NBA) and net oxyhaemoglobin absorbance (NOA) are both raised with a visible oxyhaemoglobin peak, the revised national guidelines for analysis of CSF bilirubin advise interpreting the results as ‘Consistent with subarachnoid haemorrhage (SAH)’ regardless of the CSF total protein concentration of the specimen. We wanted to study the range of CSF total protein concentrations found in confirmed SAH to establish if the CSF total protein value can give further guidance on the likelihood of SAH. Methods Consecutive cases from five different hospital sites were included if the CSF NBA was greater than 0.007 AU and the NOA was greater than 0.02 AU with a visible oxyhaemoglobin peak. For the cases identified, the laboratory information management system and patient records were interrogated to identify the total protein concentration of the CSF specimen and whether SAH had ultimately been confirmed or excluded by other methods and supporting evidence. Results Results from 132 patients were included. The CSF total protein range in confirmed SAH was 0.23–3.08 g/L with a median concentration of 0.7 g/L (n = 51). In the SAH excluded group, the CSF total protein range was 0.43–29 g/L with a median concentration of 1.9 g/L (n = 81). Conclusions Although confirmed SAH was not associated with the very highest concentrations of CSF total protein, a definite CSF protein cut-off concentration above which SAH could reliably be excluded cannot be recommended.</p

A practical guide for researchers and reviewers using the ABCD Study and other large longitudinal datasets.

As the largest longitudinal study of adolescent brain development and behavior to date, the Adolescent Brain Cognitive Development (ABCD) Study® has provided immense opportunities for researchers across disciplines since its first data release in 2018. The size and scope of the study also present a number of hurdles, which range from becoming familiar with the study design and data structure to employing rigorous and reproducible analyses. The current paper is intended as a guide for researchers and reviewers working with ABCD data, highlighting the features of the data (and the strengths and limitations therein) as well as relevant analytical and methodological considerations. Additionally, we explore justice, equity, diversity, and inclusion efforts as they pertain to the ABCD Study and other large-scale datasets. In doing so, we hope to increase both accessibility of the ABCD Study and transparency within the field of developmental cognitive neuroscience
