Musical Experience and Speech Processing: The Case of Whistled Words.

In this paper, we explore the effect of musical expertise on whistled word perception by naive listeners. In whistled words of nontonal languages, vowels are transposed to relatively stable pitches, while consonants are translated into pitch movements or interruptions. Previous behavioral studies have demonstrated that naive listeners can categorize isolated consonants, vowels, and words well over chance.

AI improves accuracy, agreement and efficiency of pathologists for Ki67 assessments in breast cancer.

The Ki-67 proliferation index (PI) guides treatment decisions in breast cancer but suffers from poor inter-rater reproducibility. Although AI tools have been designed for Ki-67 assessment, their impact on pathologists' work remains understudied. 90 international pathologists were recruited to assess the Ki-67 PI of ten breast cancer tissue microarrays with and without AI.

Machine learning in renal pathology.

Introduction: When assessing kidney biopsies, pathologists use light microscopy, immunofluorescence, and electron microscopy to describe and diagnose glomerular lesions and diseases. These methods can be laborious, costly, fraught with inter-observer variability, and can have delays in turn-around time. Thus, computational approaches can be designed as screening and/or diagnostic tools, potentially relieving pathologist time, healthcare resources, while also having the ability to identify novel biomarkers, including subvisual features.

Quantification of titanium and zirconium elements in oral mucosa around healthy dental implants: a case-control pilot study.

Objectives: Metallic particles are detected in different sites of the oral cavity, mainly in patients with peri-implantitis lesions. The aim of this pilot study was to analyze the levels of titanium and zirconium elements in the oral mucosa around healthy implants and to investigate the impact of titanium exogenous contamination on the measurements.

Materials And Methods: Forty-one participants were included in this three-phase study.

Opioid prescribing practices in trauma patients at discharge: An exploratory retrospective chart analysis.

This study examined the opioid prescribing patterns at discharge in the trauma center of a major Canadian hospital and compared them to the guidelines provided by the Illinois surgical quality improvement collaborative (ISQIC), a framework that has been recognized as being associated with reduced risk. This was a retrospective chart review of patient data from the trauma registry between January 1, 2018, and October 31, 2019. A total of 268 discharge charts of naïve opioid patients were included in the analysis.

Testing perceptual flexibility in speech through the categorization of whistled Spanish consonants by French speakers.

Whistled speech is a form of modified speech where, in non-tonal languages, vowels and consonants are augmented and transposed to whistled frequencies, simplifying their timbre. According to previous studies, these transformations maintain some level of vowel recognition for naive listeners. Here, in a behavioral experiment, naive listeners' capacities for the categorization of four whistled consonants (/p/, /k/, /t/, and /s/) were analyzed.

Mental health support for Canadian postsecondary students during COVID-19 pandemic: An environmental scan.

Objective: This study explored how Canada's postsecondary institutions have informed students about campus mental health (MH) services via websites and social media during the COVID-19 pandemic.

Methods: We conducted a Web-based environmental scan of 20 universities and 24 colleges across the province of Ontario, Canada, between October 2020 and July 2021.

Results: 91% of the institutions offered virtual counseling services and 84% offered general psychoeducational resources, whereas only 55% had COVID-19 specific MH resources.

Impact of artificial intelligence on pathologists' decisions: an experiment.

Objective: The accuracy of artificial intelligence (AI) in medicine and in pathology in particular has made major progress but little is known on how much these algorithms will influence pathologists' decisions in practice. The objective of this paper is to determine the reliance of pathologists on AI and to investigate whether providing information on AI impacts this reliance.

Materials And Methods: The experiment using an online survey design.

Smartphone Alcohol Use Disorder Recovery Apps: Cross-sectional Survey of Behavioral Intention to Use.

Background: Alcohol use disorder (AUD) carries a huge health and economic cost to society. Effective interventions exist but numerous challenges limit their adoption, especially in a pandemic context. AUD recovery apps (AUDRA) have emerged as a potential complement to in-person interventions.

A Flute, Musical Bows and Bamboo Clarinets that "Speak" in the Amazon Rainforest; Speech and Music in the Gavião Language of Rondônia.

The Gavião, a native Amazonian group in Rondônia, Brazil, use three different traditional musical instruments that they identify as "speaking" ones and that are characterized by a very tight music-lyric relation through similar pitch patterns: a flute (called ), a pair of mouth bows (), and three large bamboo clarinets (), played by three different players, each one playing a single-note clarinet. They show in different ways the relation of acoustic iconicity which exists between the words of the songs' lyrics and the music played on such instruments to "sing" the songs. Linguistic analysis makes it possible to understand the phonetic and phonological nature of the iconicity.

User Reviews of Depression App Features: Sentiment Analysis.

Background: Mental health in general, and depression in particular, remain undertreated conditions. Mobile health (mHealth) apps offer tremendous potential to overcome the barriers to accessing mental health care and millions of depression apps have been installed and used. However, little is known about the effect of these apps on a potentially vulnerable user population and the emotional reactions that they generate, even though emotions are a key component of mental health.

Evaluation of an Online System for Routine Outcome Monitoring: Cross-sectional Survey Study.

Background: The use of routine outcome monitoring (ROM) in the treatment of mental health has emerged as a method of improving psychotherapy treatment outcomes. Despite this, very few clinicians regularly use ROM in clinical practice. Online ROM has been suggested as a solution to increase adoption.

The Relevance of Human Whistled Languages for the Analysis and Decoding of Dolphin Communication.

Humans use whistled communications, the most elaborate of which are commonly called "whistled languages" or "whistled speech" because they consist of a natural type of speech. The principle of whistled speech is straightforward: people articulate words while whistling and thereby transform spoken utterances by simplifying them, syllable by syllable, into whistled melodies. One of the most striking aspects of this whistled transformation of words is that it remains intelligible to trained speakers, despite a reduced acoustic channel to convey meaning.

An evaluation of cleaning practices at a teaching hospital.

Background: The COVID-19 outbreak has highlighted the role of hospital-acquired infections in spreading epidemics. Adequately cleaning surfaces in patient rooms is an essential part of this fight to reduce the spread. Traditional audits, however, are insufficient.

Glucose point-of-care meter operators competency: An assessment checklist.

Background And Objectives: Glucose point-of-care testing meters are essential technology ubiquitous in hospitals. They are operated by non-specialized staff who are assessed through an auto-recertification process that is dependent on operators successfully producing expected outcomes. Alternatively, we suggest that operator practices be directly observed using a competency assessment checklist.

Loss of NifQ Leads to Accumulation of Porphyrins and Altered Metal-Homeostasis in Nitrogen-Fixing Symbioses.

Symbiotic nitrogen fixation between legumes and rhizobia involves a coordinated expression of many plant and bacterial genes as well as finely tuned metabolic activities of micro- and macrosymbionts. In spite of such complex interactions, symbiotic proficiency remains a resilient process, with host plants apparently capable of compensating for some deficiencies in rhizobia. What controls nodule homeostasis is still poorly understood and probably varies between plant species.

Reducing language to rhythm: Amazonian Bora drummed language exploits speech rhythm for long-distance communication.

Many drum communication systems around the world transmit information by emulating tonal and rhythmic patterns of spoken languages in sequences of drumbeats. Their rhythmic characteristics, in particular, have not been systematically studied so far, although understanding them represents a rare occasion for providing an original insight into the basic units of speech rhythm as selected by natural speech practices directly based on beats. Here, we analyse a corpus of Bora drum communication from the northwest Amazon, which is nowadays endangered with extinction.

The Influence of Telepathology on Coordination Practices.

Background: Coordination between physicians and allied professionals is essential to the effective delivery of care services and is associated with positive patient outcomes. As information technology can radically transform how professionals collaborate, both researchers and healthcare accreditation bodies are devoting a growing interest to the means of achieving better coordination.

Introduction: The primary aim of this study is to explain the extent to which and how coordination practices between pathologists, technologists, and surgeons are transformed when telepathology is being implemented.

Categorization of Natural Whistled Vowels by Naïve Listeners of Different Language Background.

Whistled speech in a non-tonal language consists of the natural emulation of vocalic and consonantal qualities in a simple modulated whistled signal. This special speech register represents a natural telecommunication system that enables high levels of sentence intelligibility by trained speakers and is not directly intelligible to naïve listeners. Yet, it is easily learned by speakers of the language that is being whistled, as attested by the current efforts of the revitalization of whistled Spanish in the Canary Islands.

Telepathology Impacts and Implementation Challenges: A Scoping Review.

Context: Telepathology is a particular form of telemedicine that fundamentally alters the way pathology services are delivered. Prior reviews in this area have mostly focused on 2 themes, namely technical feasibility issues and diagnosis accuracy.

Objectives: To synthesize the literature on telepathology implementation challenges and broader organizational and societal impacts and to propose a research agenda to guide future efforts in this domain.

Impacts of a Large Decentralized Telepathology Network in Canada.

Background: Telepathology is a fast growing segment of the telemedicine field. As of yet, no prior research has investigated the impacts of large decentralized telepathology projects on patients, clinicians, and healthcare systems. This study aims to fill this gap.

The Eastern Québec Telepathology Network: a three-year experience of clinical diagnostic services.

Background: The Eastern Quebec Telepathology Network (called Réseau de Télépathologie de l'Est du Québec in French) was created to provide uniform diagnostic telepathology services in a huge territory with low population density. We report our first 3-year experience.

Methods: The network was funded equally by the Québec ministry of Health and Canada Health Infoway, a federal telehealth funding agency.

Speech recognition in natural background noise.

In the real world, human speech recognition nearly always involves listening in background noise. The impact of such noise on speech signals and on intelligibility performance increases with the separation of the listener from the speaker. The present behavioral experiment provides an overview of the effects of such acoustic disturbances on speech perception in conditions approaching ecologically valid contexts.
