RESUMO

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.

RESUMO

Sensory gating is a process by which the brain filters out redundant information to preserve neural resources for behaviorally relevant stimuli. Although studies have shown alterations in auditory and visual processing in children who are hard-of-hearing (CHH) relative to children with normal hearing (CNH), it is unclear whether these alterations extend to the somatosensory domain, and how aberrations in sensory processing affect sensory gating. In this study, CHH and CNH were presented with a paired-pulse median nerve stimulation during magnetoencephalography. Stimulus-related gamma neural activity was imaged and virtual time series from peak somatosensory responses were extracted. We found significant effects of both stimulus and group, as well as a significant group-by-stimulus interaction. CHH showed a larger response to stimulation overall, as well as greater differences in gamma power from the first to the second stimulus. However, when looking at the ratio rather than the absolute difference in power, CHH showed comparable gating to CNH. In addition, smaller gating ratios were correlated with better classroom behavior and verbal ability in CHH, but not CNH. Taken together, these data underscore the importance of considering how CHH experience their multisensory environment when interpreting outcomes and designing interventions.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: The objective of this study was to characterize the dynamics of real-time lexical access, including lexical competition among phonologically similar words, and spreading semantic activation in school-age children with hearing aids (HAs) and children with cochlear implants (CIs). We hypothesized that developing spoken language via degraded auditory input would lead children with HAs or CIs to adapt their approach to spoken word recognition, especially by slowing down lexical access. DESIGN: Participants were children ages 9- to 12-years old with normal hearing (NH), HAs, or CIs. Participants completed a Visual World Paradigm task in which they heard a spoken word and selected the matching picture from four options. Competitor items were either phonologically similar, semantically similar, or unrelated to the target word. As the target word unfolded, children's fixations to the target word, cohort competitor, rhyme competitor, semantically related item, and unrelated item were recorded as indices of ongoing lexical access and spreading semantic activation. RESULTS: Children with HAs and children with CIs showed slower fixations to the target, reduced fixations to the cohort competitor, and increased fixations to the rhyme competitor, relative to children with NH. This wait-and-see profile was more pronounced in the children with CIs than the children with HAs. Children with HAs and children with CIs also showed delayed fixations to the semantically related item, although this delay was attributable to their delay in activating words in general, not to a distinct semantic source. CONCLUSIONS: Children with HAs and children with CIs showed qualitatively similar patterns of real-time spoken word recognition. Findings suggest that developing spoken language via degraded auditory input causes long-term cognitive adaptations to how listeners recognize spoken words, regardless of the type of hearing device used. Delayed lexical access directly led to delays in spreading semantic activation in children with HAs and CIs. This delay in semantic processing may impact these children's ability to understand connected speech in everyday life.

RESUMO

OBJECTIVES: The purpose of this study was to determine if traditional audiologic measures (e.g., pure-tone average, speech recognition) and audibility-based measures predict risk for spoken language delay in children who are hard of hearing (CHH) who use hearing aids (HAs). Audibility-based measures included the Speech Intelligibility Index (SII), HA use, and auditory dosage, a measure of auditory access that weighs each child's unaided and aided audibility by the average hours of HA use per day. The authors also sought to estimate values of these measures at which CHH would be at greater risk for delayed outcomes compared with a group of children with typical hearing (CTH) matched for age and socioeconomic status, potentially signaling a need to make changes to a child's hearing technology or intervention plan. DESIGN: The authors compared spoken language outcomes of 182 CHH and 78 CTH and evaluated relationships between language and audiologic measures (e.g., aided SII) in CHH using generalized additive models. They used these models to identify values associated with falling below CTH (by > 1.5 SDs from the mean) on language assessments, putting CHH at risk for language delay. RESULTS: Risk for language delay was associated with aided speech recognition in noise performance (<59% phonemes correct, 95% confidence interval [55%, 62%]), aided Speech Intelligibility Index (SII < 0.61, 95% confidence internal [.53,.68]), and auditory dosage (dosage < 6.0, 95% confidence internal [5.3, 6.7]) in CHH. The level of speech recognition in quiet, unaided pure-tone average, and unaided SII that placed children at risk for language delay could not be determined due to imprecise estimates with broad confidence intervals. CONCLUSIONS: Results support using aided SII, aided speech recognition in noise measures, and auditory dosage as tools to facilitate clinical decision-making, such as deciding whether changes to a child's hearing technology are warranted. Values identified in this article can complement other metrics (e.g., unaided hearing thresholds, aided speech recognition testing, language assessment) when considering changes to intervention, such as adding language supports, making HA adjustments, or referring for cochlear implant candidacy evaluation.

RESUMO

PURPOSE: The purpose of this study was to measure how parent concern about childhood hearing loss varies under different description conditions: classification-based, audibility-based, and simulation-based descriptions. METHOD: We randomly allocated study participants (n = 143) to complete an online survey about expected child difficulties with listening situations with hearing loss. Our participants were parents of children with typical hearing in the 0- to 12-month age range. Participants were exposed to one type of description (classification-based, audibility-based, or simulation-based) and one level of hearing loss (slight, mild, and moderate or their audibility and simulation equivalents), producing nine total groups. Participants rated the level of expected difficulty their child would experience performing age-appropriate listening tasks with the given hearing loss. They also selected what they perceived as the most appropriate intervention from a list of increasingly intense options. RESULTS: Our findings revealed that audibility-based descriptions elicited significantly higher levels of parent concerns about hearing loss than classification-based strategies, but that simulation-based descriptions elicited the highest levels of concern. Those assigned to simulation-based and audibility-based groups also judged relatively more intense intervention options as appropriate compared to those assigned to classification-based groups. CONCLUSIONS: This study expands our knowledge base about descriptive factors that impact levels of parent concern about hearing loss after diagnosis. This has potentially cascading effects on later intervention actions such as fitting hearing technology. It also provides a foundation for developing and testing clinical applications of audibility-based counseling strategies.

RESUMO

HIV disclosure to sexual partners remains a multifaceted yet stigmatised process. The 'undetectable equals untransmittable' (U = U) concept has raised ethical and moral concerns about the obligation and need to disclose, and using Internet applications to seek sex partners has modified disclosure practices. While previous qualitative literature has examined the HIV disclosure process, there is a dearth of information on this topic among gay men in the USA who have an undetectable viral load. Using thematic analysis of data collected during a period of expanded U = U knowledge, this study explores the cognitive, contextual, interpersonal and structural factors impacting undetectable gay men's HIV status disclosure decisions to sexual partners. In-depth interviews were conducted in August 2020 over Zoom with 20 gay men with undetectable viral loads. The main themes included 'sense of obligation,' 'situational disclosure' and 'partners' responsibility in the disclosure process.' Participants balanced the aforementioned factors to inform their disclosure decisions, and disclosure patterns varied across participants dependent upon thoughts regarding ethics and morality of (non-)disclosure. The findings provide new insights to how participants navigate disclosure while considering U = U, HIV criminalisation laws, and finding partners through Internet applications while providing direction for future studies and support for decriminalising HIV and expanding HIV education.

RESUMO

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.

RESUMO

OBJECTIVE: Paediatric hearing-aid verification relies on measures of output obtained from the ear canal or in a coupler with the child's real-ear-to-coupler difference (RECD). Measured RECD cannot always be completed in children, leading to fitting inaccuracies. Audiologists often have tympanometry data that characterises the child's ear-canal acoustics. The goal of this study was to determine if tympanometry can be used to improve predictions of measured RECD. DESIGN: A retrospective analysis of RECD and admittance, tympanometric peak pressure, and equivalent ear-canal volume from 226 Hz tympanometry collected as part of a longitudinal study of children with hearing loss were modelled with Bayesian hierarchical regression. STUDY SAMPLE: Two-hundred sixty-six children with mild-to-severe hearing loss contributed data. RESULTS: Age-based average RECD models were within 3 dB of measured RECD values in 54% of cases with normal middle ear status and 50.6% of cases with abnormal middle ear status. Immittance-predicted RECD were within 3 dB in 69.6% of cases with normal middle ear status and 74.4% of cases with abnormal middle ear status. CONCLUSION: Immittance-predicted RECD was more accurate than age-based average RECD, particularly in children with abnormal middle ear status. The findings suggest that 226 Hz tympanometry could be used clinically to improve predictions of measured RECD when it cannot be measured.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: The impact of COVID-19 on swallowing function is not well understood. Despite low hospital admission rates in Australia, the virus and subsequent treatment affects swallow function in those requiring intensive care unit (ICU) treatment. As such, the current pandemic provides a unique opportunity to describe swallowing function and outline dysphagia characteristics and trajectory of recovery for a series of cases across NSW. AIM: The aims of this study were to describe (i) physiological characteristics of swallowing dysfunction and (ii) pattern of swallowing recovery and outcomes, in ICU patients with COVID-19. METHODS: All patients admitted to 17 participating NSW Health ICU sites over a 12-month period (March 2020-March 2021), diagnosed with COVID-19, treated with the aim for survival, and seen by a speech pathologist for clinical swallowing examination during hospital admission were considered for inclusion. Demographic, critical care airway management, speech pathology treatment, and swallowing outcome data were collected. RESULTS: Twenty-seven patients (22 male; 5 female) with a median age of 65 years (interquartile range [IQR] = 15.5) were recruited. All required mechanical ventilation. Almost 90% of the total cohort had pre-existing comorbidities, with the two most frequently observed being diabetes (63%, 95% confidence interval = 44%-78%) and cardiac disease (59%, 95% confidence interval = 40%-75%) in origin. Prevalence of dysphagia was 93%, with the majority (44%) exhibiting profound dysphagia at the initial assessment. Median duration to initiate oral feeding was 38.5 days (IQR = 31.25) from ICU admission, and 33% received dysphagia rehabilitation. Dysphagia recovery was observed in 81% with a median duration of 44 days (IQR = 29). Positive linear associations were identified between duration of intubation, mechanical ventilation, hospital and ICU length of stay, and the duration to speech pathology assessment (p < 0.005), dysphagia severity (p < 0.002), commencing oral intake (p < 0.02), dysphagia recovery (p < 0.004), and enteral feeding (p < 0.024). CONCLUSION: COVID-19 considerably impacted swallowing function in the current study. Although many patients recovered within an acceptable timeframe, some experienced persistent severe dysphagia and a protracted recovery with dependence on enteral nutrition.

RESUMO

While studying polyvictimization is well established within the broader violence literature and applied to other types of violence, it has yet to be documented whether polyvictimization also presents in patterns of police violence exposure (i.e., neglectful, psychological, physical, and sexual police violence). Our objective was to analyze latent patterns of co-occurring police contact and their associations with mental health. By applying latent class analysis (LCA) methods to the 2016 and 2017 Surveys of Police-Public Encounters (N = 2615), conducted in 4 Northeastern US cities, we identified classes of direct and vicarious police violence and compared sociodemographic characteristics among classes using multinomial regression. Classes were regressed on mental health outcomes. LCA identified four classes of police contact. Compared to Positive Police Contact (33.0%) class members, members of the (a) Extreme Police Violence (4.0%) class reported higher anticipation of future police victimization, psychological distress, and suicide ideations and attempts; they were more likely to be Black, cisgender men, and Latinx; (b) members of the High Police Violence (23.6%) class reported higher anticipation of future police victimization and psychological distress; they were more likely to be Black, Native American, and multiracial; members of the (c) Low Police Contact (39.5%) class had comparable mental health outcomes; they were more likely to report a household income < $19,999. Notably, no participants were unexposed to police contact. Polyvictimization presents in experiences of police violence and disproportionately impacts structurally marginalized people.

RESUMO

OBJECTIVE: Children who are hard of hearing (CHH) experience delays in spoken language and executive function, but the mechanisms for these deficits remain unresolved. Differences in auditory experience and language skills have been examined as contributing factors to deficits in executive function, primarily with children who are deaf and children with cochlear implants. The theoretical model of cumulative auditory experience quantifies auditory dosage as how much speech is audible and how often children wear their hearing aids. CHH with higher auditory dosage have better language outcomes than peers with less auditory dosage. However, the effects of auditory experience on executive function have not been studied in CHH. The goal of this study was to examine the influences of auditory experience and language skills on the development of executive function in CHH. DESIGN: We collected measures of aided speech audibility, hearing aid use, executive function, and receptive vocabulary in 177 CHH and 86 children with typical hearing who were 5- to 10 years old and matched for socioeconomic status and nonverbal intelligence. Auditory dosage was calculated by combining each child's average hours of hearing aid use with their audibility for speech to create a variable that quantifies individual differences in auditory access. RESULTS: CHH had lower receptive vocabulary and deficits in executive function related to working memory and selective attention compared to peers with typical hearing. CHH with greater auditory dosage had higher receptive vocabulary than CHH with lower auditory dosage. Better receptive vocabulary was associated with better scores on executive function measures related to working memory and attention. Auditory dosage was also directly associated with measures of verbal working memory. CONCLUSIONS: CHH have deficits in language and some, but not all, areas of executive function related to working memory and attention. Auditory dosage was associated with language abilities and verbal working memory. Language was associated with individual differences in executive function skills related to attention and working memory. These results provide support for systems theories regarding the development of executive function in CHH. Interventions that improve auditory access and language may be effective for improving executive function related to working memory and attention in CHH.

RESUMO

OBJECTIVES: Children with hearing loss (CHL) may exhibit spoken language delays and may also experience deficits in other cognitive domains including working memory. Consistent hearing aid use (i.e., more than 10 hours per day) ameliorates these language delays; however, the impact of hearing aid intervention on the neural dynamics serving working memory remains unknown. The objective of this study was to examine the association between the amount of hearing aid use and neural oscillatory activity during verbal working memory processing in children with mild-to-severe hearing loss. DESIGN: Twenty-three CHL between 8 and 15 years-old performed a letter-based Sternberg working memory task during magnetoencephalography (MEG). Guardians also completed a questionnaire describing the participants' daily hearing aid use. Each participant's MEG data was coregistered to their structural MRI, epoched, and transformed into the time-frequency domain using complex demodulation. Significant oscillatory responses corresponding to working memory encoding and maintenance were independently imaged using beamforming. Finally, these whole-brain source images were correlated with the total number of hours of weekly hearing aid use, controlling for degree of hearing loss. RESULTS: During the encoding period, hearing aid use negatively correlated with alpha-beta oscillatory activity in the bilateral occipital cortices and right precentral gyrus. In the occipital cortices, this relationship suggested that with greater hearing aid use, there was a larger suppression of occipital activity (i.e., more negative relative to baseline). In the precentral gyrus, greater hearing aid use was related to less synchronous activity (i.e., less positive relative to baseline). During the maintenance period, hearing aid use significantly correlated with alpha activity in the right prefrontal cortex, such that with greater hearing aid use, there was less right prefrontal maintenance-related activity (i.e., less positive relative to baseline). CONCLUSIONS: This study is the first to investigate the impact of hearing aid use on the neural dynamics that underlie working memory function. These data show robust relationships between the amount of hearing aid use and phase-specific neural patterns during working memory encoding and maintenance after controlling for degree of hearing loss. Furthermore, our data demonstrate that wearing hearing aids for more than ~8.5 hours/day may serve to normalize these neural patterns. This study also demonstrates the potential for neuroimaging to help determine the locus of variability in outcomes in CHL.

RESUMO

BACKGROUND: Extreme, prolonged wildfire smoke (WFS) events are becoming increasingly frequent phenomena across the Western United States. Rural communities, dependent on contributions of nature to people's quality of life, are particularly hard hit. While prior research has explored the physical health impacts of WFS exposure, little work has been done to assess WFS impacts on mental health and wellbeing, or potential adaptation solutions. METHODS: Using qualitative methods, we explore the mental health and wellbeing impacts experienced by community members in a rural Washington State community that has been particularly hard hit by WFS in recent years, as well as individual, family, and community adaptation solutions. We conducted focus groups with residents and key informant interviews with local health and social service providers. RESULTS: Participants identified a variety of negative mental health and wellbeing impacts of WFS events, including heightened anxiety, depression, isolation, and a lack of motivation, as well as physical health impacts (e.g., respiratory issues and lack of exercise). Both positive and negative economic and social impacts, as well as temporary or permanent relocation impacts, were also described. The impacts were not equitably distributed; differential experiences based on income level, outdoor occupations, age (child or elderly), preexisting health conditions, housing status, and social isolation were described as making some residents more vulnerable to WFS-induced physical and mental health and wellbeing challenges than others. Proposed solutions included stress reduction (e.g., meditation and relaxation lessons), increased distribution of air filters, development of community clean air spaces, enhancing community response capacity, hosting social gatherings, increasing education, expanding and coordination risk communications, and identifying opportunities for volunteering. Findings were incorporated into a pamphlet for community distribution. We present a template version herein for adaptation and use in other communities. CONCLUSIONS: Wildfire smoke events present significant mental health and wellbeing impacts for rural communities. Community-led solutions that promote stress reduction, physical protection, and community cohesion have the opportunity to bolster resilience amid this growing public health crisis.

RESUMO

Understanding how phenotypes evolve requires disentangling the effects of mutation generating new variation from the effects of selection filtering it. Tests for selection frequently assume that mutation introduces phenotypic variation symmetrically around the population mean, yet few studies have tested this assumption by deeply sampling the distributions of mutational effects for particular traits. Here, we examine distributions of mutational effects for gene expression in the budding yeast Saccharomyces cerevisiae by measuring the effects of thousands of point mutations introduced randomly throughout the genome. We find that the distributions of mutational effects differ for the 10 genes surveyed and are inconsistent with normality. For example, all 10 distributions of mutational effects included more mutations with large effects than expected for normally distributed phenotypes. In addition, some genes also showed asymmetries in their distribution of mutational effects, with new mutations more likely to increase than decrease the gene's expression or vice versa. Neutral models of regulatory evolution that take these empirically determined distributions into account suggest that neutral processes may explain more expression variation within natural populations than currently appreciated.
