ABSTRACT
BACKGROUND: Dietary supplements can modulate the gut microbial ecosystem and affect the immune system. This has potential implications for autoimmune diseases, including multiple sclerosis (MS). Prior studies explored tolerability, symptomatic improvement, and immunologic effects of probiotics in people with MS (pwMS), but no study has examined prebiotics in this population or compared prebiotics with probiotics. METHODS: This is a randomized, open-label trial of participants with relapsing-remitting MS on B-cell depletion therapy from two MS centers. 22 participants enrolled in the original cross-over study in which probiotic (Visbiome, containing Lactobacillus, Bifidobacterium and Streptococcus species) or prebiotic (Prebiotin, containing oligofructose enriched inulin) supplementation for 6 weeks was randomized, each followed by a washout period. Due to pandemic-related interruptions and expiration of the study supply of probiotics, another 15 participants enrolled in a single-arm study to receive prebiotic supplementation for 6 weeks followed by a washout period. We assessed supplement tolerability and patient-reported outcomes (PRO) relevant to MS (disability, fatigue, mood, and bowel symptoms) before and after each supplement administration period and each washout period. We bio-archived plasma, serum, peripheral blood mononuclear cells and stool samples at each timepoint for future multi-omic assessment. RESULTS: Prebiotics and probiotics had comparable adherence rates and both supplements were well tolerated in pwMS. Participants on either supplement reported minor adverse events, most of which were mild and self-limited. There was a subjective preference for prebiotics over probiotics. Comparing supplement-associated changes in PRO scores from baseline to 6 weeks post-supplementation, there were significant difference between prebiotics and probiotics for the change in patient-reported global symptom burden (MSRS-R Total) and bowel control (BWCS), but only probiotics statistically improved bowel control from baseline to post-supplementation. CONCLUSION: Supplementation with either prebiotics or probiotics is reasonably well-tolerated and safe. Probiotics improved bowel control, but did not improve other PROs in a 6-week time frame. These data regarding feasibility, tolerability, adherence, and adverse events of supplements will inform future clinical trial designs to definitively compare the efficacy and safety of prebiotics and probiotics. The biological data that will be generated from this study in the future will provide mechanistic insights into the effects of these dietary supplements on MS pathophysiology.

PURPOSE: The purpose of the 12-month randomized controlled trial was to evaluate the effectiveness of a Telephonic Self-Management Support (T-SMS) program among adults with type 2 diabetes (T2D). METHODS: Eight hundred twelve adults with T2D participated in NYC Care Calls (mean age = 59.2, SD = 10.8; female = 57%; mean A1C = 9.3, SD = 1.8; Latino = 86%) and were randomly assigned to T-SMS or enhanced usual care (EUC). A1C (primary outcome), blood pressure, and body mass index (secondary outcomes) were extracted from electronic medical records. Secondary patient-reported outcomes, including depressive symptoms, diabetes distress, medication adherence, and self-management activities, were assessed by telephone in English or Spanish. For T-SMS, the number of assigned phone calls was based on baseline A1C, depressive symptoms, and/or diabetes distress. Analyses were conducted under the intention-to-treat principle. RESULTS: A1C decreased over 12 months in both T-SMS (0.72% percentage points; 95% CI, 0.53-0.91) and EUC (0.66% percentage points; 95% CI, 0.46-0.85; Ps < .001). Diabetes distress and self-management also improved over time in both arms (Ps < .05). Compared to EUC, participants in the T-SMS arm did not differ in outcomes. CONCLUSIONS: The T-SMS and EUC groups were found not to have an appreciable outcome difference. It is unclear whether improvements in A1C across both conditions represent a secular trend or indicate that print-based educational intervention may have a positive impact on self-management and well-being.

Recent implementation science frameworks highlight the role of training and technical assistance (TTA) in building workforce capacity to implement evidence-based practices (EBPs). However, evaluation of TTA is limited. We describe three case examples that highlight TTA by three regional centers in the national Mental Health Technology Transfer Center (MHTTC) network. Each MHTTC formed Learning Communities (LCs) to facilitate connections among behavioral health professionals with the goals of sharing implementation strategies, discussing best-practices, and developing problem solving techniques. Data on outcomes were collected through a combination of self-report surveys and qualitative interviews. LC participants reported strong connectedness, gains in knowledge and skills, improvements in implementation capacity, and intentions to advocate for organizational and systems-level change. Furthermore, across the case examples, we identified LC characteristics that are associated with participant perceptions of outcomes, including tailoring LC content to workforce needs, providing culturally relevant information, engaging leaders, forming connections among participants and trainers, and challenging participants' current workplace practices. These findings are interpreted through the lens of the Interactive Systems Framework, which focuses on how TTA, such as LCs, can facilitate connections between the theoretical and empirical foundations of interventions and the practices of implementing interventions in real-world settings to advance workforce capacity.

BACKGROUND: Previous studies have shown that thalamic and hippocampal neurodegeneration is associated with clinical decline in Multiple Sclerosis (MS). However, contributions of the specific thalamic nuclei and hippocampal subfields require further examination. OBJECTIVE: Using 7 Tesla (7T) magnetic resonance imaging (MRI), we investigated the cross-sectional associations between functionally grouped thalamic nuclei and hippocampal subfields volumes and T1 relaxation times (T1-RT) and subsequent clinical outcomes in MS. METHODS: High-resolution T1-weighted and T2-weighted images were acquired at 7T (n=31), preprocessed, and segmented using the Thalamus Optimized Multi Atlas Segmentation (THOMAS, for thalamic nuclei) and the Automatic Segmentation of Hippocampal Subfields (ASHS, for hippocampal subfields) packages. We calculated Pearson correlations between hippocampal subfields and thalamic nuclei volumes and T1-RT and subsequent multi-modal rater-determined and patient-reported clinical outcomes (â¼2.5 years after imaging acquisition), correcting for confounders and multiple tests. RESULTS: Smaller volume bilaterally in the anterior thalamus region correlated with worse performance in gait function, as measured by the Patient Determined Disease Steps (PDDS). Additionally, larger volume in most functional groups of thalamic nuclei correlated with better visual information processing and cognitive function, as measured by the Symbol Digit Modalities Test (SDMT). In bilateral medial and left posterior thalamic regions, there was an inverse association between volumes and T1-RT, potentially indicating higher tissue degeneration in these regions. We also observed marginal associations between the right hippocampal subfields (both volumes and T1-RT) and subsequent clinical outcomes, though they did not survive correction for multiple testing. CONCLUSION: Ultrahigh field MRI identified markers of structural damage in the thalamic nuclei associated with subsequently worse clinical outcomes in individuals with MS. Longitudinal studies will enable better understanding of the role of microstructural integrity in these brain regions in influencing MS outcomes.

OBJECTIVES: We provide a novel application of psycholinguistic theories and methods to the field of auditory training to provide preliminary data regarding which minimal pair contrasts are more difficult for listeners with typical hearing to distinguish in real-time. DESIGN: Using eye-tracking, participants heard a word and selected the corresponding image from a display of four: the target word, two unrelated words, and a word from one of four contrast categories (i.e., voiced-initial [e.g., peach-beach], voiced-final [e.g., back-bag], manner-initial [e.g., talk-sock], and manner-final [e.g., bat-bass]). RESULTS: Fixations were monitored to measure how strongly words compete for recognition depending on the contrast type (voicing, manner) and location (word-initial or final). Manner contrasts competed more for recognition than did voicing contrasts, and contrasts that occurred in word-final position were harder to distinguish than word-initial position. CONCLUSION: These results are an important initial step toward creating an evidence-based hierarchy for auditory training for individuals who use cochlear implants.

BACKGROUND: The burden of non-adherence to anti-tuberculosis (TB) treatment is poorly understood. One type is early discontinuation, that is, stopping treatment early. Given the implications of early discontinuation for treatment outcomes, we undertook a systematic review to estimate its burden, using the timing of loss to follow-up (LFU) as a proxy measure. METHODS: Web of Science, Embase and Medline were searched up to 14 January 2021 using terms covering LFU, TB and treatment. Studies of adults (≥ 18 years) on the standard regimen for drug-sensitive TB reporting the timing of LFU (WHO definition) were included. A narrative synthesis was conducted and quality assessment undertaken using an adapted version of Downs and Black. Papers were grouped by the percentage of those who were ultimately LFU who were LFU by 2 months. Three groups were created: <28.3% LFU by 2 months, ≥28.3-<38.3%, ≥38.3%). The percentage of dose-months missed due to early discontinuation among (1) those LFU, and (2) all patients was calculated. RESULTS: We found 40 relevant studies from 21 countries. The timing of LFU was variable within and between countries. 36/40 papers (90.0%) reported the percentage of patients LFU by the end of 2 months. 31/36 studies (86.1%) reported a higher than or as expected percentage of patients becoming LFU by 2 months. The percentage of dose-months missed by patients who became LFU ranged between 37% and 77% (equivalent to 2.2-4.6 months). Among all patients, the percentage of dose-months missed ranged between 1% and 22% (equivalent to 0.1-1.3 months). CONCLUSIONS: A larger than expected percentage of patients became LFU within the first 2 months of treatment. These patients missed high percentages of dose months of treatment due to early discontinuation. Interventions to promote adherence and retain patients in care must not neglect the early months of treatment. PROSPERO REGISTRATION NUMBER: CRD42021218636.

BACKGROUND: Laryngeal mask airway surfactant administration (S-LMA) has the potential benefit of surfactant administration whilst avoiding endotracheal intubation and ventilation, ventilator-induced lung injury and bronchopulmonary dysplasia (BPD). OBJECTIVES: To evaluate the benefits and harms of S-LMA either as prophylaxis or treatment (rescue) compared to placebo, no treatment, or intratracheal surfactant administration via an endotracheal tube (ETT) with the intent to rapidly extubate (InSurE) or extubate at standard criteria (S-ETT) or via other less-invasive surfactant administration (LISA) methods on morbidity and mortality in preterm infants with or at risk of respiratory distress syndrome (RDS). SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, and three trial registries in December 2022. SELECTION CRITERIA: Randomised controlled trials (RCTs), cluster- or quasi-RCTs of S-LMA compared to placebo, no treatment, or other routes of administration (nebulised, pharyngeal instillation of surfactant before the first breath, thin endotracheal catheter surfactant administration or intratracheal surfactant instillation) on morbidity and mortality in preterm infants at risk of RDS. We considered published, unpublished and ongoing trials. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion and extracted data. We used GRADE to assess the certainty of the evidence. MAIN RESULTS: We included eight trials (seven new to this update) recruiting 510 newborns. Five trials (333 infants) compared S-LMA with surfactant administration via ETT with InSurE. One trial (48 infants) compared S-LMA with surfactant administration via ETT with S-ETT, and two trials (129 infants) compared S-LMA with no surfactant administration. We found no studies comparing S-LMA with LISA techniques or prophylactic or early S-LMA. S-LMA versus surfactant administration via InSurE S-LMA may have little or no effect on the composite outcome of death or BPD at 36 weeks' postmenstrual age (risk ratio (RR) 1.50, 95% confidence interval (CI) 0.27 to 8.34, I 2 = not applicable (NA) as 1 study had 0 events; risk difference (RD) 0.02, 95% CI -0.07 to 0.10; I 2 = 0%; 2 studies, 110 infants; low-certainty evidence). There may be a reduction in the need for mechanical ventilation at any time (RR 0.53, 95% CI 0.36 to 0.78; I 2 = 27%; RD -0.14, 95% CI -0.22 to -0.06, I 2 = 89%; number needed to treat for an additional beneficial outcome (NNTB) 7, 95% CI 5 to 17; 5 studies, 333 infants; low-certainty evidence). However, this was limited to four studies (236 infants) using analgesia or sedation for the InSurE group. There was little or no difference for air leak during first hospitalisation (RR 1.39, 95% CI 0.65 to 2.98; I 2 = 0%; 5 studies, 333 infants (based on 3 studies as 2 studies had 0 events); low-certainty evidence); BPD among survivors to 36 weeks' PMA (RR 1.28, 95% CI 0.47 to 3.52; I 2 = 0%; 4 studies, 264 infants (based on 3 studies as 1 study had 0 events); low-certainty evidence); or death (all causes) during the first hospitalisation (RR 0.28, 95% CI 0.01 to 6.60; I 2 = NA as 2 studies had 0 events; 3 studies, 203 infants; low-certainty evidence). Neurosensory disability was not reported. Intraventricular haemorrhage ( IVH) grades III and IV were reported among the study groups (1 study, 50 infants). S-LMA versus surfactant administration via S-ETT No study reported death or BPD at 36 weeks' PMA. S-LMA may reduce the use of mechanical ventilation at any time compared with S-ETT (RR 0.47, 95% CI 0.31 to 0.71; RD -0.54, 95% CI -0.74 to -0.34; NNTB 2, 95% CI 2 to 3; 1 study, 48 infants; low-certainty evidence). We are very uncertain whether S-LMA compared with S-ETT reduces air leak during first hospitalisation (RR 2.56, 95% CI 0.11 to 59.75), IVH grade III or IV (RR 2.56, 95% CI 0.11 to 59.75) and death (all causes) during the first hospitalisation (RR 0.17, 95% CI 0.01 to 3.37) (1 study, 48 infants; very low-certainty evidence). No study reported BPD to 36 weeks' PMA or neurosensory disability. S-LMA versus no surfactant administration Rescue surfactant could be used in both groups. There may be little or no difference in death or BPD at 36 weeks (RR 1.65, 95% CI 0.85 to 3.22; I 2 = 58%; RD 0.08, 95% CI -0.03 to 0.19; I 2 = 0%; 2 studies, 129 infants; low-certainty evidence). There was probably a reduction in the need for mechanical ventilation at any time with S-LMA compared with nasal continuous positive airway pressure without surfactant (RR 0.57, 95% CI 0.38 to 0.85; I 2 = 0%; RD -0.24, 95% CI -0.40 to -0.08; I 2 = 0%; NNTB 4, 95% CI 3 to 13; 2 studies, 129 infants; moderate-certainty evidence). There was little or no difference in air leak during first hospitalisation (RR 0.65, 95% CI 0.23 to 1.88; I 2 = 0%; 2 studies, 129 infants; low-certainty evidence) or BPD to 36 weeks' PMA (RR 1.65, 95% CI 0.85 to 3.22; I 2 = 58%; 2 studies, 129 infants; low-certainty evidence). There were no events in either group for death during the first hospitalisation (1 study, 103 infants) or IVH grade III and IV (1 study, 103 infants). No study reported neurosensory disability. AUTHORS' CONCLUSIONS: In preterm infants less than 36 weeks' PMA, rescue S-LMA may have little or no effect on the composite outcome of death or BPD at 36 weeks' PMA. However, it may reduce the need for mechanical ventilation at any time. This benefit is limited to trials reporting the use of analgesia or sedation in the InSurE and S-ETT groups. There is low- to very-low certainty evidence for no or little difference in neonatal morbidities and mortality. Long-term outcomes are largely unreported. In preterm infants less than 32 weeks' PMA or less than 1500 g, there are insufficient data to support or refute the use of S-LMA in clinical practice. Adequately powered trials are required to determine the effect of S-LMA for prevention or early treatment of RDS in extremely preterm infants. S-LMA use should be limited to clinical trials in this group of infants.

Few studies examined blood biomarkers informative of patient-reported outcome (PRO) of disability in people with multiple sclerosis (MS). We examined the associations between serum multi-protein biomarker profiles and patient-reported MS disability. In this cross-sectional study (2017-2020), adults with diagnosis of MS (or precursors) from two independent clinic-based cohorts were divided into a training and test set. For predictors, we examined seven clinical factors (age at sample collection, sex, race/ethnicity, disease subtype, disease duration, disease-modifying therapy [DMT], and time interval between sample collection and closest PRO assessment) and 19 serum protein biomarkers potentially associated with MS disease activity endpoints identified from prior studies. We trained machine learning (ML) models (Least Absolute Shrinkage and Selection Operator regression [LASSO], Random Forest, Extreme Gradient Boosting, Support Vector Machines, stacking ensemble learning, and stacking classification) for predicting Patient Determined Disease Steps (PDDS) score as the primary endpoint and reported model performance using the held-out test set. The study included 431 participants (mean age 49 years, 81% women, 94% non-Hispanic White). For binary PDDS score, combined feature input of routine clinical factors and the 19 proteins consistently outperformed base models (comprising clinical features alone or clinical features plus one single protein at a time) in predicting severe (PDDS ≥ 4) versus mild/moderate (PDDS < 4) disability across multiple machine learning approaches, with LASSO achieving the best area under the curve (AUCPDDS = 0.91) and other metrics. For ordinal PDDS score, LASSO model comprising combined clinical factors and 19 proteins as feature input (R2PDDS = 0.31) again outperformed base models. The two best-performing LASSO models (i.e., binary and ordinal PDDS score) shared six clinical features (age, sex, race/ethnicity, disease subtype, disease duration, DMT efficacy) and nine proteins (cluster of differentiation 6, CUB-domain-containing protein 1, contactin-2, interleukin-12 subunit-beta, neurofilament light chain [NfL], protogenin, serpin family A member 9, tumor necrosis factor superfamily member 13B, versican). By comparison, LASSO models with clinical features plus one single protein at a time as feature input did not select either NfL or glial fibrillary acidic protein (GFAP) as a final feature. Forcing either NfL or GFAP as a single protein feature into models did not improve performance beyond clinical features alone. Stacking classification model using five functional pathways to represent multiple proteins as meta-features implicated those involved in neuroaxonal integrity as significant contributors to predictive performance. Thus, serum multi-protein biomarker profiles improve the prediction of real-world MS disability status beyond clinical profile alone or clinical profile plus single protein biomarker, reaching clinically actionable performance.
ABSTRACT
OBJECTIVES: The purpose of this study was to evaluate effects of masker type and hearing group on the relationship between school-age children's speech recognition and age, vocabulary, working memory, and selective attention. This study also explored effects of masker type and hearing group on the time course of maturation of masked speech recognition. DESIGN: Participants included 31 children with normal hearing (CNH) and 41 children with mild to severe bilateral sensorineural hearing loss (CHL), between 6.7 and 13 years of age. Children with hearing aids used their personal hearing aids throughout testing. Audiometric thresholds and standardized measures of vocabulary, working memory, and selective attention were obtained from each child, along with masked sentence recognition thresholds in a steady state, speech-spectrum noise (SSN) and in a two-talker speech masker (TTS). Aided audibility through children's hearing aids was calculated based on the Speech Intelligibility Index (SII) for all children wearing hearing aids. Linear mixed effects models were used to examine the contribution of group, age, vocabulary, working memory, and attention to individual differences in speech recognition thresholds in each masker. Additional models were constructed to examine the role of aided audibility on masked speech recognition in CHL. Finally, to explore the time course of maturation of masked speech perception, linear mixed effects models were used to examine interactions between age, masker type, and hearing group as predictors of masked speech recognition. RESULTS: Children's thresholds were higher in TTS than in SSN. There was no interaction of hearing group and masker type. CHL had higher thresholds than CNH in both maskers. In both hearing groups and masker types, children with better vocabularies had lower thresholds. An interaction of hearing group and attention was observed only in the TTS. Among CNH, attention predicted thresholds in TTS. Among CHL, vocabulary and aided audibility predicted thresholds in TTS. In both maskers, thresholds decreased as a function of age at a similar rate in CNH and CHL. CONCLUSIONS: The factors contributing to individual differences in speech recognition differed as a function of masker type. In TTS, the factors contributing to individual difference in speech recognition further differed as a function of hearing group. Whereas attention predicted variance for CNH in TTS, vocabulary and aided audibility predicted variance in CHL. CHL required a more favorable signal to noise ratio (SNR) to recognize speech in TTS than in SSN (mean = +1 dB in TTS, -3 dB in SSN). We posit that failures in auditory stream segregation limit the extent to which CHL can recognize speech in a speech masker. Larger sample sizes or longitudinal data are needed to characterize the time course of maturation of masked speech perception in CHL.

Data collected during the 2020-21 COVID-19 alpha wave indicated dysphagia prevalence rates up to 93%. Whilst many patients recovered during hospital admission, some experienced persistent dysphagia with protracted recovery. To explore (1) prevalence, (2) treatment, and (3) recovery patterns and outcomes for swallowing, in the ICU patient with Delta and subsequent variants of COVID-19. Prospective observational study. Patients admitted to 26 Intensive Care Units (ICUs) over 12 months, diagnosed with COVID-19, treated for survival and seen by Speech-Language Pathology (SLP) for clinical swallowing assessment were included. Demographic, medical, SLP treatment, and swallowing outcome data were collected. 235 participants (63% male, median age = 58 years) were recruited. Median mechanical ventilation was 16 days, and ICU and hospital length of stay (LOS) were 20 and 42 days, respectively. ICU-Acquired Weakness (54%) and delirium (49%) were frequently observed. Prevalence of dysphagia was 94% with the majority (45%) exhibiting profound dysphagia (Functional Oral Intake Scale = 1) at initial assessment. Median duration to initiate oral feeding was 19 days (IQR = 11-44 days) from ICU admission, and 24% received dysphagia rehabilitation. Dysphagia recovery by hospital discharge was observed in 71% (median duration = 30 days [IQR = 17-56 days]). Positive linear associations were identified between duration of intubation, mechanical ventilation, hospital and ICU LOS, and duration to SLP assessment (p = 0.000), dysphagia severity (p = 0.000), commencing oral intake (p = 0.000), dysphagia recovery (p < 0.01), and enteral feeding (p = 0.000). Whilst older participants had more severe dysphagia (p = 0.028), younger participants took longer to commence oral feeding (p = 0.047). Dysphagia remains highly prevalent in ICU COVID-19 patients. Whilst invasive ventilation duration is associated with swallowing outcomes, more evidence on dysphagia pathophysiology is required to guide rehabilitation.

BACKGROUND: Dysphonia and laryngeal pathology are considerable issues in patients hospitalised with COVID-19 with prevalence rates cited between 29% and 79%. Most studies currently are limited to reporting single-institution data with many retrospective. OBJECTIVES: The aims of this study were to prospectively explore the following: (i) prevalence; (ii) treatment; and (iii) recovery pattern and outcomes for dysphonia, in patients with COVID-19 requiring intensive care unit (ICU) treatment. METHODS: Patients admitted to 26 ICUs over 12 months, diagnosed with COVID-19, treated for survival, and seen by speech-language pathology for clinical voice assessment were considered. Demographic, medical, speech-language pathology treatment, and voice outcome data (grade, roughness, breathiness, asthenia, strain [GRBAS]) were collected on initial consultation and continuously monitored throughout the hospital admission. FINDINGS: Two-hundred and thirty five participants (63% male, median age = 58 yrs) were recruited. Median mechanical ventilation duration and ICU and hospital lengths of stay (LOSs) were 16, 20, and 42 days, respectively. Dysphonia prevalence was 72% (170/235), with 22% (38/170) exhibiting profound impairment (GRBAS score = 3). Of those with dysphonia, rehabilitation was provided in 32% (54/170) cases, with dysphonia recovery by hospital discharge observed in 66% (112/170, median duration = 35 days [interquartile range = 21-61 days]). Twenty-five percent (n = 42) of patients underwent nasendoscopy: oedema (40%, 17/42), granuloma (31%, 13/42), and vocal fold palsy/paresis (26%, 11/42). Presence of dysphonia was inversely associated with the number of intubations (p = 0.002), intubation duration (p = 0.037), ICU LOS (p = 0.003), and hospital LOS (p = 0.009). Conversely, duration of dysphonia was positively associated with the number of intubations (p = 0.012), durations of intubation (p = 0.000), tracheostomy (p = 0.004), mechanical ventilation (p = 0.000), ICU LOS (p = 0.000), and hospital LOS (p = 0.000). More severe dysphonia was associated with younger age (p = 0.045). Proning was not associated with presence (p = 0.075), severity (p = 0.164), or duration (p = 0.738) of dysphonia. CONCLUSIONS: Dysphonia and laryngeal pathology are common in critically ill patients with COVID-19 and are associated with younger age and protracted recovery in those with longer critical care interventions.

OBJECTIVE: To determine if a stricter criterion for paediatric hearing aid fitting for proximity of fit-to-target of <3 dB root-mean-square (RMS) error produces better audibility and outcomes compared to the current <5 dB criterion, and to examine the relationship between aided audibility and RMS error by degree of hearing loss. DESIGN: We evaluated the influence of unaided hearing level on the relationship between RMS error and aided audibility. We assessed the effect of RMS error category (<3, 3-5, >5 dB) on aided audibility, speech recognition, expressive vocabulary, and morphosyntax. STUDY SAMPLE: The study included 2314 hearing aid verification measurements from 307 children with hearing aids. RESULTS: Children who met a <3 dB criterion had higher aided audibility than children who met no criterion (>5 dB error). Results showed no differences in speech recognition or vocabulary by error category, but children with <3 dB error demonstrated better morphosyntax than children with 3-5 and >5 dB RMS error. CONCLUSIONS: Fittings that are close to prescriptive targets provide a more positive outcome for children with hearing aids. Using probe microphone measures to adjust hearing aids to within 3 dB may benefit language abilities in children.
ABSTRACT
OBJECTIVE: The COVID-19 pandemic exacerbated risk for poor mental health (MH) outcomes among youth from low-income families and propelled a shift to telemental health. Yet, little is known about barriers to and facilitators of MH care access when services are delivered via synchronous telehealth to Medicaid-enrolled youth. STUDY DESIGN: Between December 2020 and March 2021, we conducted in-depth interviews with 19 therapists from a large safety-net organization who served Medicaid-enrolled youth (< 18 years of age) to elucidate their perspectives on barriers to and facilitators of access to telemental health services among this population. METHODS: We conducted a thematic content analysis, guided by the 5 dimensions of health care access identified by Fortney and colleagues: geographical, temporal, digital, cultural (including acceptability of services), and financial access. RESULTS: Therapists noted that when components of digital access are met (ie, access to hardware and software, connectivity, and technological literacy), then telehealth could facilitate temporal access and eliminate geographic barriers; elimination of these barriers was particularly beneficial for youth in rural and hard-to-reach communities. Notably, many families depended on smartphones for telemental health access, and many youth depended on their caregiver's smartphone. When considering acceptability of services, some youth preferred in-person services, whereas other youth (especially some teenagers with high technological literacy) had a preference for telemental health. CONCLUSIONS: Our results highlight the need for flexibility in reimbursement policies that allows providers to optimize MH care access by offering telehealth delivered via telephone and video as well as in-person services, depending on the needs and preferences of youth and families.

Individual differences in ear-canal acoustics introduce variability into hearing aid output that can affect speech audibility. Measuring ear-canal acoustics in young children can be challenging, and relying on normative real-ear-to-coupler difference (RECD) transforms can lead to large fitting errors. Acoustic immittance measures characterize the impedance of the ear and are more easily measured than RECD. Using 226 Hz tympanometry to predict the RECD is more accurate than using age-based average RECD values. The current study sought to determine whether wideband acoustic immittance measurements could improve predictions of wideband real-ear-to-coupler difference (wRECD). 150 children ages 2-10 years with intact tympanic membranes underwent wRECD and wideband acoustic immittance measures in each ear. Three models were constructed to predict each child's measured wRECD: the age-based average wRECD, 226 Hz admittance wRECD, and wideband absorbance wRECD. The average age-based wRECD model predicted the child's measured wRECD within 3 dB in 62% of cases, but both the 226 Hz admittance and wideband absorbance wRECD were within 3 dB in 90% of cases. Using individual 226 Hz or wideband absorbance to predict wRECD improved the accuracy and precision of transforms used for pediatric hearing aid fitting.

PURPOSE: The primary goal for this study was to compare story generation and narrative retell performance in children who are hard of hearing (CHH) and hearing children. A secondary goal was to determine factors that influence narrative performance. Research on this topic is important because narrative language competency is an essential communication function. METHOD: Participants included 86 CHH and 53 seven-year-old hearing children who had completed a test battery composed of vocabulary, grammar, phonological processing, story generation, and narrative retell tasks. Coders who were blind to hearing status used a scoring rubric to judge the quality of narrative macrostructure in story generation and narrative retells. Data were analyzed using analysis of variance to determine group differences and correlational models to examine individual differences. RESULTS: At 7 years of age, CHH demonstrated significant deficits in narrative macrostructure compared to hearing children, with larger delays in narrative retell than story generation. Vocabulary, grammar, and phonological memory acted as mediators in the relationship between hearing status and story generation; grammar acted as a mediator between hearing status and narrative retell. Auditory access variables accounted for a significant proportion of shared variance in story generation skills for CHH. CONCLUSIONS: School-age CHH are at risk for delays in narrative production, particularly with retelling stories. The results of this study highlight a narrative coding approach and task procedures that are sensitive to differences in language levels and may be clinically useful for professionals working with early school-age children.

AIMS: People with type 2 diabetes (T2DM) have an increased risk of cardiovascular disease (CVD). We examined depressive symptoms (DS) and diabetes distress (DD) in relation to the estimated 10-year risk of CVD in adults with T2DM enrolled in the GRADE Emotional Distress Substudy. METHODS: Linear regression models examined the associations of baseline DS and DD with estimated 10-year risk of CVD using the Atherosclerotic Cardiovascular Disease (ASCVD) risk score, adjusting for age, sex, race/ethnicity, education, income, diabetes duration, diabetes-related complications, and HbA1c. RESULTS: A total of 1,605 GRADE participants were included: 54% Non-Latino (NL) White, 18% Latino, 19% NL-Black, 66% male, mean age 57.5 (SD = 10.25) years, diabetes duration 4.2 (SD = 2.8) years, and HbA1c 7.5% (SD = 0.5%). After incorporating covariates, only DS, especially cognitive-affective symptoms, were associated with ASCVD risk (estimate = 0.15 [95% CI: 0.04, 0.025], p = 0.006). Higher DS remained significantly associated with higher ASCVD risk when adding DD to covariates (estimate = 0.19 [95% CI: 0.07, 0.30], p = 0.002). DD was not associated with ASCVD risk when accounting for covariates. CONCLUSIONS: Depressive symptoms, particularly cognitive-affective symptoms, are associated with increased 10-year predicted ASCVD risk among adults with early T2DM. Diabetes distress is not significantly associated with the predicted ASCVD risk when accounting for covariates.

AIM: To identify the barriers associated with inadequate antenatal attendance by disadvantaged women in Australia and to further explore how these barriers are experienced by this population group. DESIGN: A qualitative descriptive study utilizing semi-structured interviews and thematic analysis. METHODS: Interviews were conducted with 11 pregnant women who self-identified as experiencing disadvantage, purposively sampled from a local government area of Victoria, Australia, characterized by socio-economic disadvantage. Data were collected from February to July 2019. RESULTS: Study participants reported a range of barriers to receiving timely and adequate antenatal care (ANC). For several women, a combination of personal (e.g., emotions, knowledge), health service provision (e.g., limited access to continuity of care provider and continuity of information, inflexible scheduling, difficulty travelling, staff attitudes), and broader social-contextual factors (e.g., financial situation, language, cultural norms) were ultimately insurmountable. Whereas some barriers were experienced as hassles or annoyances, others were unacceptable, overwhelming, or humiliating. CONCLUSION: Women experiencing disadvantage in Australia value ANC but face multiple and complex barriers that undermine timely and regular access. IMPLICATIONS FOR THE PROFESSION AND/PATIENT CARE: A wide range of strategies targeting barriers across multiple levels of the social-ecological environment are required if ANC attendance rates are to improve and ultimately redress existing health disparities. Various continuity of care models are well-placed to address many of the identified barriers and should be made more accessible to women, and particularly those women experiencing disadvantage. IMPACT: Antenatal care appointments promote the health of women and their babies during pregnancy, but for many women, particularly those experiencing disadvantage, access is delayed or inadequate. ANC providers play a critical role in facilitating timely and adequate care. Health service practitioners and management, and health services policymakers need to understand the complexity of the barriers women encounter. These stakeholders can utilize the findings reported herein to develop more effective strategies for overcoming multiple and multi-level barriers. REPORTING METHOD: The study is reported in accordance with the relevant EQUATOR guidelines: the standards for reporting qualitative research (SRQR) and consolidated criteria for reporting qualitative research (COREQ). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Adolescent relationship abuse (ARA) (i.e. physical, sexual, psychological, or economic abuse in the context of romantic relationships) is associated with adverse health outcomes, including anxiety, depression, suicidality, unintended pregnancy, and substance misuse. A related phenomenon, reproductive coercion involves interference with the reproductive decision making of a partner with the intention of promoting pregnancy or controlling outcomes of a pregnancy. Reproductive coercion is associated with unintended pregnancy, partner violence, and sexually transmitted infections. Little is known about the intersection between economic ARA, sexual exploitation, and reproductive coercion. This paper explores the intersections between reproductive coercion, transactional sex, and economic abuse victimization in adolescent dating relationships. In an online survey, 1,752 adolescents (ages 13-17) were asked about economic adolescent relationship abuse (educational, employment and financial interference), transactional sex, reproductive coercion, and contraceptive access within their relationships. We assessed associations with chi-square tests and logistic regression analysis. Youth who experienced economic ARA (70%, 1,232) reported financial dependence on their partner, contraceptive access, and reproductive coercion (74-83%; p-values<0.001) more often than their counterparts without economic ARA. Adolescents experiencing economic abuse were more likely to report transactional sex (aOR = 2.76, CI [2.12, 3.60], p < .001), depending on a partner to pay for contraception or birth control (aOR = 2.20, CI [1.71, 2.84], p < .001), and reproductive coercion (aOR = 3.20, CI [2.37, 4.32], p < .001). Youth-serving providers and agencies should be aware of intersections between economic ARA, transactional sex, financial dependence, and reproductive coercion, particularly for adolescents with health-related social needs.

We review the literature related to Patricia Stelmachowicz's research in pediatric audiology, specifically focusing on the influence of audibility in language development and acquisition of linguistic rules. Pat Stelmachowicz spent her career increasing our awareness and understanding of children with mild to severe hearing loss who use hearing aids. Using a variety of novel experiments and stimuli, Pat and her colleagues produced a robust body of evidence to support the hypothesis that development moderates the role of frequency bandwidth on speech perception, particularly for fricative sounds. The prolific research that came out of Pat's lab had several important implications for clinical practice. First, her work highlighted that children require access to more high-frequency speech information than adults in the detection and identification of fricatives such as /s/ and /z/. These high-frequency speech sounds are important for morphological and phonological development. Consequently, the limited bandwidth of conventional hearing aids may delay the formation of linguistic rules in these two domains for children with hearing loss. Second, it emphasized the importance of not merely applying adult findings to the clinical decision-making process in pediatric amplification. Clinicians should use evidence-based practices to verify and provide maximum audibility for children who use hearing aids to acquire spoken language.
