• SLPCase-Control2019Neonatal vitamin D status in relation to autism spectrum disorder and developmental delay in the CHARGE case-control study.Autism research : official journal of the International Society for Autism ResearchNeonatal vitamin D showed no link with autism overall. Higher levels were linked with less developmental delay in initial comparisons, but not after accounting for mother's education and weight before pregnancy. In girls, higher levels were linked with autism less often.
• SLPOther2019Polarity Sensitivity in Pediatric and Adult Cochlear Implant Listeners.Trends in hearingHow listeners heard positive versus negative electrical pulses did not differ between child- and adult-implanted cochlear implant listeners and did not predict vowel or consonant perception. It varied widely across electrodes.
• SLPOther2019Self-reported Sensory Hypersensitivity Moderates Association Between Tactile Psychophysical Performance and Autism-Related Traits in Neurotypical Adults.Journal of autism and developmental disordersTactile sensitivity alone did not predict autism traits in 42 adults. But among those reporting high sensory hypersensitivity, a narrow dynamic range for detecting vibrations was associated with increased communication difficulties and broader autism-related traits.
• SLPOther2019Predicting confrontation naming item difficulty.AphasiologyNaming speed from 44 healthy adults helped predict how hard each Philadelphia Naming Test picture is, alongside word frequency, age of acquisition and word length.
• SLPOther2019Spatial Speech-in-Noise Performance in Bimodal and Single-Sided Deaf Cochlear Implant Users.Trends in hearingBimodal and single-sided deaf cochlear implant users showed no added spatial speech-in-noise benefit from using both ears beyond the better ear alone. Normal-hearing listeners showed a large spatial benefit when both ears were used.
• SLPSurvey2019Public awareness of ear health and hearing loss in Jeddah, Saudi Arabia.The South African journal of communication disorders = Die Suid-Afrikaanse tydskrif vir KommunikasieafwykingsJeddah residents scored 10.66 of 14 on average. They knew hearing aids need fitting, but only 53.4% knew listening to music for more than 3 h a day using earphones may cause permanent hearing loss.
• SLPRCT2019Using a Bone-Conduction Headset to Improve Speech Discrimination in Children With Otitis Media With Effusion.Trends in hearingChildren with glue ear heard distant speech better with a bone-conduction headset and microphone. Quiet thresholds fell from 39 to 23 dB(A); in noise from 59 to 45. It may help during watchful waiting, but long-term benefit is unproven.
• SLPCohort2019Quantifying phonological knowledge in children with phonological disorder.Clinical linguistics & phoneticsFor preschoolers with phonological disorder, a consonant accuracy cutoff of 20.4% on a large 293-word probe correctly classifies 90.0% of sounds as present or absent in the child’s phonemic inventory. This allows clinicians to estimate functional phonological knowledge from standard accuracy scores without manual minimal-pair analysis.
• SLPOther2019Family Emotional Climate and Children with Autism Spectrum Disorder.Journal of autism and developmental disordersThe largest group of families, 43%, showed high warmth and low criticism across parent-child and couple relationships. Higher child emotional and behavioral problems and parent autism-like traits were linked to more distressed family relationships.
• SLPNarrative Review2019Community service speech language therapists practising in adult dysphagia: Is the healthcare system failing them?The South African journal of communication disorders = Die Suid-Afrikaanse tydskrif vir KommunikasieafwykingsNew speech-language therapists in South Africa often feel underprepared to manage adult dysphagia independently due to limited training and lack of supervision. The article argues that mandatory mentorship and accessible continuing education are needed to support these junior clinicians.
• OTSLPCohort2019Can the stroke impact scale 3.0 detect cognitive impairments in patients with a recent stroke?Journal of physical therapy scienceAfter stroke rehab, 41 older survivors using the Stroke Impact Scale reported trouble with memory, concentration and everyday problem solving, and many reported low mood items. The scale flagged concerns, but the study did not prove it detects cognitive impairment.
• OTSLPCohort2019Behavioral Health Service Utilization and Unmet Need After Traumatic Brain Injury in Childhood.Journal of developmental and behavioral pediatrics : JDBPYears after injury, children with traumatic brain injury had higher rates of behavioral health need than those with other injuries, but service use did not differ. Across all groups, 77% of those needing care were not receiving it. Race predicted access, with white children having higher unmet need.
• SLPOther2019Sensitivity to Interaural Phase in Older Hearing-Impaired Listeners Correlates With Nonauditory Trail Making Scores and With a Spatial Auditory Task of Unrelated Peripheral Origin.Trends in hearingIn 20 older adults with hearing loss, poor ability to detect sound timing differences correlated strongly with slow performance on a visual tracking task. This suggests the hearing test may reflect general cognitive or spatial processing speed rather than just ear damage.
• SLPOther2019Specificity of Phonological Representations for Children with Autism Spectrum Disorder.Journal of autism and developmental disordersYoung children with autism were as affected by mispronunciations as younger typically developing children, even though they recognized words less accurately overall.
• SLPOther2019Limited Pre-Speech Auditory Modulation in Individuals Who Stutter: Data and Hypotheses.Journal of speech, language, and hearing research : JSLHRAdults who stutter show absent pre-speech auditory modulation when speaking normally. However, adding a 100ms delay to their auditory feedback activates this modulation, eliminating the difference between stuttering and non-stuttering speakers. This suggests the deficit is specific to typical feedback conditions.
• SLPOther2019The Parallel Auditory Brainstem Response.Trends in hearingA new hearing test recorded brainstem responses to five frequencies in both ears at once. In normal-hearing adults, it produced standard waveforms and reached a preset noise level in a median 4.6 min, versus 30.1 min for serial testing.
• SLPOther2019Searching for the Sound of a Cochlear Implant: Evaluation of Different Vocoder Parameters by Cochlear Implant Users With Single-Sided Deafness.Trends in hearingCochlear implant users judged a pulsatile vocoder carrier closer to their implant sound than sinusoidal or noise carriers. They also preferred lower frequency mismatch, but the simulations still sounded different from the real implant.
• SLPCohort2019Reduced frontal gamma power at 24 months is associated with better expressive language in toddlers at risk for autism.Autism research : official journal of the International Society for Autism ResearchHigh-risk toddlers without later ASD had lower frontal gamma power at 24 months, and lower power was linked to better expressive language. Toddlers with ASD did not differ from low-risk controls, so this single EEG measure was not a clear ASD marker.
• SLPSurvey2019Relationship Between Subjective Reports of Temporary Threshold Shift and the Prevalence of Hearing Problems in Military Personnel.Trends in hearingService members who reported temporary muffled hearing after loud noise were more likely to report tinnitus and everyday hearing difficulties. These reports were more closely linked with hearing problems than reported exposure to continuous, firearm, or heavy weapon noise.
• SLPOther2019No Effect of Interstimulus Interval on Acoustic Reflex Thresholds.Trends in hearingLengthening the pause between sounds during acoustic reflex testing did not lower thresholds or improve reliability in young adults with normal hearing. A short 2.5-second interval is sufficient for accurate testing at both 1 kHz and 4 kHz frequencies.
• SLPNarrative Review2019Speech Production From a Developmental Perspective.Journal of speech, language, and hearing research : JSLHRThis is a theoretical review, not a test of therapy. It proposes how speech production develops and suggests ideas for future research, not evidence that any treatment works.
• SLPCohort2019Persistence of dysfunctional natural killer cells in adults with high-functioning autism spectrum disorders: stigma/consequence of unresolved early infectious events?Molecular autismAdults with high-functioning autism showed persistent natural killer cell activation and altered function, including links to language and social awareness scores. This is a biomarker association, not a tested treatment or clinical test.
• SLPCase-Control2019Impaired auditory processing and neural representation of speech in noise among symptomatic post-concussion adults.Brain injuryOverall early brain responses did not clearly differ between concussion and controls, but noise affected concussion participants more, and active listening responses to speech were poorer than controls. This does not show all concussion patients have auditory processing deficits.
• SLPCase-Control2019An In-Depth Analysis of Expository Writing in Children With and Without Autism Spectrum Disorder.Journal of autism and developmental disordersChildren with autism wrote shorter essays with more grammar errors but used more rare words. Their overall essay quality matched peers. They struggled more with starting, staying on task, and generating ideas during the writing process.
• SLPCase Series2019Impaired Lexical Selection and Fluency in Post-Stroke Aphasia.AphasiologyIn people with post-stroke aphasia, less fluent speech was linked to greater difficulty recognising words that sound similar to many other words. This suggests that trouble selecting the right word during listening may share mechanisms with trouble speaking fluently.
• SLPOther2019Abnormal auditory mismatch fields are associated with communication impairment in both verbal and minimally verbal/nonverbal children who have autism spectrum disorder.Autism research : official journal of the International Society for Autism ResearchChildren with autism, especially minimally verbal/nonverbal, had slower brain responses to changed vowel sounds. Slower responses were linked to communication and nonverbal cognitive scores. This was a study finding, not evidence of a treatment target.
• SLPOther2019Differential Altered Auditory Event-Related Potential Responses in Young Boys on the Autism Spectrum With and Without Disproportionate Megalencephaly.Autism research : official journal of the International Society for Autism ResearchIn an early brain response window, young boys with autism and normal brain size showed little graded brain response as sounds got louder. Boys with autism and disproportionately large brain volume, and typical boys, showed larger responses to louder sounds.
• OTSLPCohort2019Responsiveness, Minimal Clinically Important Difference, and Validity of the MoCA in Stroke Rehabilitation.Occupational therapy internationalMoCA scores rose significantly in 65 stroke survivors after task-oriented therapy. The smallest clinically important change was estimated at 1.22 or 2.15 points, depending on method. Relationships with some stroke impact domains were fair to good.
• SLPCohort2019Effects of Age and Noise Exposure on Proxy Measures of Cochlear Synaptopathy.Trends in hearingIn adults with normal hearing, age and estimated lifetime noise exposure did not predict brainstem or envelope-following measures thought to index cochlear synaptopathy. A speech-in-noise test showed age and noise exposure effects, but noise exposure predicted better high-level performance, not damage.
• SLPOther2019Building a Successful Voice Telepractice Program.Perspectives of the ASHA special interest groupsThis is a practice guide for setting up voice teleprograms, covering licensure, privacy, and treatment tips. It reports no patient outcomes, so there is no evidence here to support or refute any specific clinical approach.
• SLPOther2019The Medial Olivocochlear Reflex Is Unlikely to Play a Role in Listening Difficulties in Children.Trends in hearingChildren referred for listening difficulties had similar strength of a brainstem ear reflex to typical peers on several ear-canal sound tests. This does not support that reflex as a common explanation for their speech-in-noise complaints.
• PTOTSLPSystematic Review2019A Systematic Review of What Barriers and Facilitators Prevent and Enable Physical Healthcare Services Access for Autistic Adults.Journal of autism and developmental disordersAutistic adults reported healthcare barriers including communication, sensory overload, appointments, and provider assumptions. Accommodations such as written notes, quiet waiting, and individual plans were suggested; this review does not prove any single approach works.
• SLPOther2019On the Interaction of Head and Gaze Control With Acoustic Beam Width of a Simulated Beamformer in a Two-Talker Scenario.Trends in hearingGaze-steered simulated beams improved speech understanding only when the talker stayed put and the beam was narrow. When talkers switched unexpectedly, head-steered beams were better because eyes could not reorient fast enough.
• SLPOther2019Blood oxytocin concentration positively predicts contagious yawning behavior in children with autism spectrum disorder.Autism research : official journal of the International Society for Autism ResearchNo significant difference in contagious yawning was found between 34 children with autism and 30 typically developing children. Lower blood oxytocin predicted fewer contagious yawns in the autism group only. This is a biomarker association, not a treatment result.
• SLPOther2019FreeHear: A New Sound-Field Speech-in-Babble Hearing Assessment Tool.Trends in hearingA sound-field digits-in-noise test produced reliable speech-in-noise scores in children from 5 years old and adults. Children's scores improved with age, and four-year-olds often could not finish, so use age norms and expect incomplete tests in very young children.
• SLPCohort2019Clustering of co-occurring conditions in autism spectrum disorder during early childhood: A retrospective analysis of medical claims data.Autism research : official journal of the International Society for Autism ResearchYoung children with autism in claims data clustered into three groups by co-occurring medical diagnoses. All condition categories were more common than in children without autism, and 58.2% of children with autism had diagnoses in four or more categories.
• SLPPilot2019Functional Near-Infrared Spectroscopy as a Measure of Listening Effort in Older Adults Who Use Hearing Aids.Trends in hearingFor 16 older hearing aid users, wearing aids did not reduce oxygenation in the front of the brain, reaction time, self-reported effort, or accuracy during a listening task. The brain measure still tracked difficulty, rising as the memory task got harder.
• SLPNarrative Review2019Diagnosing and Preventing Hearing Loss in the Genomic Age.Trends in hearingFor children with hearing loss, genetic testing can identify causes, guide counseling, and flag syndromic risks. Rapid testing for a mitochondrial variant may help clinicians avoid aminoglycoside antibiotics in babies at risk of drug-induced deafness.
• SLPCase Report2019Language mixing patterns in a bilingual individual with non-fluent aphasia.AphasiologyIn one bilingual man with non-fluent aphasia, language mixing was more frequent when speaking English than Hebrew, in single-word naming than connected speech, and for function words such as pronouns. Verb versus noun did not differ.
• SLPSurvey2019Autistic traits in adults who have attempted suicide.Molecular autismAdults who reported more than one suicide attempt scored higher on autistic traits than those reporting one attempt. When age, sex and diagnosed or suspected conditions were considered, the link was not clear.
• SLPOther2019Comparing Tinnitus Tuning Curves and Psychoacoustic Tuning Curves.Trends in hearingTinnitus was usually harder to mask than a matching tone, and most tinnitus masking curves did not show the sharp tuning seen for external tones.
• SLPPilot2019Predicting aggression to others in youth with autism using a wearable biosensor.Autism research : official journal of the International Society for Autism ResearchWearable biosensor data predicted aggression in the next minute with 84% average accuracy in 20 inpatient youth with autism, but this pilot did not test whether alerts reduce aggression.
• SLPOther2019Hearing Difficulties and Tinnitus in Construction, Agricultural, Music, and Finance Industries: Contributions of Demographic, Health, and Lifestyle Factors.Trends in hearingConstruction and farm workers had more difficulty hearing speech in noise than finance workers. Tinnitus differences by industry were associated with noise exposure and age, not the industry itself.
• SLPOther2019Perception of Auditory Distance in Normal-Hearing and Moderate-to-Profound Hearing-Impaired Listeners.Trends in hearingAdding early reflections to hearing aid remote microphone systems made speech sound externalized in over 90% of tests. Hearing aids with compression did not harm distance perception, and optimizing audibility mattered more than preserving spatial cues.
• SLPOther2019Mechanisms of voice control related to prosody in autism spectrum disorder and first-degree relatives.Autism research : official journal of the International Society for Autism ResearchPeople with autism made larger voice corrections when their feedback pitch was shifted down or up. Parents, especially those with autism-like social traits, showed similar patterns. Their voice feedback responses were atypical and related to prosody differences.
• SLPCase Series2019Electroencephalography in Primary Progressive Aphasia and Apraxia of Speech.AphasiologyEEG was normal in patients with primary progressive apraxia of speech without aphasia, but showed theta slowing in those with aphasia. In nonfluent/agrammatic progressive aphasia, slowing was also seen except in one patient with excess beta activity.
• SLPOther2019Comparing Three Established Methods for Tinnitus Pitch Matching With Respect to Reliability, Matching Duration, and Subjective Satisfaction.Trends in hearingNo tinnitus pitch-matching method was best on every measure. Forced-choice matching varied most and was rated least satisfying. Likeness rating was steady but slowest, and tone adjustment may bias matched pitch lower.
• SLPOther2019High-Frequency Sensorineural Hearing Loss Alters Cue-Weighting Strategies for Discriminating Stop Consonants in Noise.Trends in hearingAdults with high-frequency hearing loss relied less on high-frequency speech cues than normal-hearing listeners, even with simulated hearing aids. They leaned more on low-frequency cues. This fits persistent consonant-in-noise difficulty despite amplification.
• SLPOther2019Effects of Acquired Aphasia on the Recognition of Speech Under Energetic and Informational Masking Conditions.Trends in hearingPeople with aphasia did worse than age-matched controls at picking out target words from two competing talkers. Their quiet comprehension and hearing profiles were similar, so the difficulty was tied to competing speech.
• SLPOther2019Discrimination of Gain Increments in Speech.Trends in hearingSmall overall gain changes to speech can be noticed, but frequency-specific changes are much harder to hear. Patients may not notice small hearing-aid fine-tuning changes, especially at high frequencies. This is not evidence that changes improve outcomes.
