RESUMO

Explaining individual differences in vocabulary in autism is critical, as understanding and using words to communicate are key predictors of long-term outcomes for autistic individuals. Differences in audiovisual speech processing may explain variability in vocabulary in autism. The efficiency of audiovisual speech processing can be indexed via amplitude suppression, wherein the amplitude of the event-related potential (ERP) is reduced at the P2 component in response to audiovisual speech compared to auditory-only speech. This study used electroencephalography (EEG) to measure P2 amplitudes in response to auditory-only and audiovisual speech and norm-referenced, standardized assessments to measure vocabulary in 25 autistic and 25 nonautistic children to determine whether amplitude suppression (a) differs or (b) explains variability in vocabulary in autistic and nonautistic children. A series of regression analyses evaluated associations between amplitude suppression and vocabulary scores. Both groups demonstrated P2 amplitude suppression, on average, in response to audiovisual speech relative to auditory-only speech. Between-group differences in mean amplitude suppression were nonsignificant. Individual differences in amplitude suppression were positively associated with expressive vocabulary through receptive vocabulary, as evidenced by a significant indirect effect observed across groups. The results suggest that efficiency of audiovisual speech processing may explain variance in vocabulary in autism.

RESUMO

Children with autism show alterations in multisensory integration that have been theoretically and empirically linked with the core and related features of autism. It is unclear, however, to what extent multisensory integration maps onto features of autism within children with and without autism. This study, thus, evaluates relations between audiovisual integration and core and related autism features across children with and without autism. Thirty-six children reported perceptions of the McGurk illusion during a psychophysical task. Parents reported on participants' autistic features. Increased report of illusory percepts tended to covary with reduced autistic features and greater communication skill. Some relations, though, were moderated by group. This work suggests that associations between multisensory integration and higher-order skills are present, but in some instances vary according to diagnostic group.

RESUMO

Autistic children show reduced multisensory integration of audiovisual speech stimuli in response to the McGurk illusion. Previously, it has been shown that adults can integrate sung McGurk tokens. These sung speech tokens offer more salient visual and auditory cues, in comparison to the spoken tokens, which may increase the identification and integration of visual speech cues in autistic children. Forty participants (20 autism, 20 non-autistic peers) aged 7-14 completed the study. Participants were presented with speech tokens in four modalities: auditory-only, visual-only, congruent audiovisual, and incongruent audiovisual (i.e., McGurk; auditory 'ba' and visual 'ga'). Tokens were also presented in two formats: spoken and sung. Participants indicated what they perceived via a four-button response box (i.e., 'ba', 'ga', 'da', or 'tha'). Accuracies and perception of the McGurk illusion were calculated for each modality and format. Analysis of visual-only identification indicated a significant main effect of format, whereby participants were more accurate in sung versus spoken trials, but no significant main effect of group or interaction effect. Analysis of the McGurk trials indicated no significant main effect of format or group and no significant interaction effect. Sung speech tokens improved identification of visual speech cues, but did not boost the integration of visual cues with heard speech across groups. Additional work is needed to determine what properties of spoken speech contributed to the observed improvement in visual accuracy and to evaluate whether more prolonged exposure to sung speech may yield effects on multisensory integration.

RESUMO

OBJECTIVES: This study aims to assess characteristics of same-day clinic appointments in a pediatric population at an academic otolaryngology practice. METHODS: Retrospective chart review of patients aged 18 or younger who had same-day clinic appointments between January 1, 2016, and December 31, 2018, at a single academic institution. Demographic data, diagnosis(es), procedures, and operations completed were included in the analysis. RESULTS: There were 363 same-day visits by 322 patients in the 3-year study period. Two hundred sixty-nine (269) of these visits were from new patients. Otitis media and rhinosinusitis were the most frequently coded diagnoses. One hundred forty-four (144) procedures were completed the day of the visit and 169 operations were performed as a result of the same-day visit. If the patient had a procedure or operation performed, they were more likely to have been referred by another provider. CONCLUSIONS: Providing same-day appointments can help provide timely and appropriate otolaryngology specialty care to pediatric patients. Further evaluation is needed to determine the effects on patient satisfaction as well as no-show rates.

RESUMO

INTRODUCTION: Interrogation of cancers with next-generation sequencing (NGS) mutation panels has become widely utilized, identifying prognostic and actionable mutations. This study explored the value of expanded mutation analysis in appendix peritoneal metastases (APM). METHODS: Forty-eight APM patients treated 2013-2018 were retrospectively collected from a registry. Fifty-gene NGS analysis was performed in CLIA approved lab to obtain mutation profiles. All patients underwent cytoreductive surgery (CRS)/hyperthermic intraperitoneal chemotherapy (HIPEC) with mitomycin C. Peritoneal cancer index (PCI), optimal CRS, survival (overall survival [OS] and progression-free survival [PFS]) data were collected. Survival analyses were performed on all APM, high-grade (HG), and low grade (LG) subsets, evaluating the impact of specific mutations on the outcome. RESULTS: Eighty-three percent of APM had a mutation identified. KRAS was most frequent, 65% (88% LG 42% HG) with GNAS identified in 92% of LG-APM. SMAD4 and/or TP53 mutations occurred in 25% of APM with observed decreased OS (46 vs. 81 months p = .0029); worse in HG-APM (26 vs. 49 months p = .0451). SMAD4 was associated with the most significant reduction in PFS in APM (p = .0085). Actionable mutations were identified in 73% of APM patients. CONCLUSIONS: Most frequent mutations were KRAS, TP53, and SMAD4, and actionable mutation detection was common. SMAD4 and TP53 were associated with decreased OS. NGS mutation profiling has potential utility in APM.

RESUMO

Children with autism spectrum disorder (ASD) display differences in multisensory function as quantified by several different measures. This study estimated the stability of variables derived from commonly used measures of multisensory function in school-aged children with ASD. Participants completed: a simultaneity judgment task for audiovisual speech, tasks designed to elicit the McGurk effect, listening-in-noise tasks, electroencephalographic recordings, and eye-tracking tasks. Results indicate the stability of indices derived from tasks tapping multisensory processing is variable. These findings have important implications for measurement in future research. Averaging scores across repeated observations will often be required to obtain acceptably stable estimates and, thus, to increase the likelihood of detecting effects of interest, as it relates to multisensory processing in children with ASD.

RESUMO

BACKGROUND: Many children with autism spectrum disorder (ASD) demonstrate atypical responses to multisensory stimuli. These disruptions, which are frequently seen in response to audiovisual speech, may produce cascading effects on the broader development of children with ASD. Perceptual training has been shown to enhance multisensory speech perception in typically developed adults. This study was the first to examine the effects of perceptual training on audiovisual speech perception in children with ASD. METHOD: A multiple baseline across participants design was utilized with four 7- to 13-year-old children with ASD. The dependent variable, which was probed outside the training task each day using a simultaneity judgment task in baseline, intervention, and maintenance conditions, was audiovisual temporal binding window (TBW), an index of multisensory temporal acuity. During perceptual training, participants completed the same simultaneity judgment task with feedback on their accuracy after each trial in easy-, medium-, and hard-difficulty blocks. RESULTS: A functional relation between the multisensory perceptual training program and TBW size was not observed. Of the three participants who were entered into training, one participant demonstrated a strong effect, characterized by a fairly immediate change in TBW trend. The two remaining participants demonstrated a less clear response (i.e., longer latency to effect, lack of functional independence). The first participant to enter the training condition demonstrated some maintenance of a narrower TBW post-training. CONCLUSIONS: Results indicate TBWs in children with ASD may be malleable, but additional research is needed and may entail further adaptation to the multisensory perceptual training paradigm.

RESUMO

Research shows that children with autism spectrum disorder (ASD) differ in their behavioral patterns of responding to sensory stimuli (i.e., sensory responsiveness) and in various other aspects of sensory functioning relative to typical peers. This study explored relations between measures of sensory responsiveness and multisensory speech perception and integration in children with and without ASD. Participants were 8-17 year old children, 18 with ASD and 18 matched typically developing controls. Participants completed a psychophysical speech perception task, and parents reported on children's sensory responsiveness. Psychophysical measures (e.g., audiovisual accuracy, temporal binding window) were associated with patterns of sensory responsiveness (e.g., hyporesponsiveness, sensory seeking). Results indicate that differences in multisensory speech perception and integration covary with atypical patterns of sensory responsiveness.

RESUMO

BACKGROUND: Data relating high-sensitivity cardiac troponin T (hs-cTnT) to long-term myocardial function and infarct size in patients after ST-elevation myocardial infarction (STEMI) are lacking. We aimed to evaluate the use of early hs-cTnT concentrations for prediction of myocardial function and infarct size assessed by cardiac magnetic resonance imaging (CMR) one year following STEMI. METHODS: Sixty-six patients, revascularized by primary percutaneous coronary intervention (PCI) for first-time STEMI, were enrolled in this observational study. Serial hs-cTnT, creatine kinase (CK), high-sensitivity C-reactive protein (hs-CRP) and lactate dehydrogenase (LDH) levels were measured on admission, 6 h, 12 h, and 24 h post-PCI. Patients underwent CMR within the first week and 12months thereafter. RESULTS: Except for admission hs-cTnT, all single time point and peak hs-cTnT concentrations showed significant correlations with left ventricular ejection fraction (LVEF: r=-0.404 to -0.517, all ps<0.01) and infarct size (IS: r=0.421 to 0.700, all ps<0.01) at baseline and follow-up. The area under the curve (AUC) of peak hs-cTnT was 0.82 (95% CI 0.71-0.92) for the prediction of decreased LVEF (<55%) and 0.89 (95% CI 0.81-0.97) for the prediction of large IS (>8%) at 12months. The combination of all four biomarkers resulted in an AUC of 0.82 and 0.92 for the prediction of reduced LVEF and large IS at 12months, respectively (both ps>0.05). CONCLUSION: In stable STEMI patients successfully revascularized by primary PCI, serial and peak concentrations of hs-cTnT are closely correlated to long-term LVEF and IS. Combination of hs-cTnT with CK, hs-CRP, or LDH did not add any significant prognostic value as compared with hs-cTnT alone.

RESUMO

BACKGROUND: In patients with ST-elevation myocardial infarction (STEMI), the relationship between transaminases and myocardial damage detected by cardiac magnetic resonance (CMR) imaging is unknown and the prognostic value incompletely investigated. MATERIALS AND METHODS: CMR imaging was performed in 167 STEMI patients 2.3 [1.6-3.9] days after primary percutaneous coronary intervention (PPCI). Blood samples for transaminase measurement (aspartate transaminase (AST) and alanine transaminase (ALT)) were obtained serially from day 1 to day 4 after PPCI. Patients were followed for major adverse cardiac events (MACE) for 2.7 [1.1-3.3] years. RESULTS: Admission and peak concentrations of AST and ALT were significantly associated with ejection fraction (p < 0.001), infarct size (p < 0.001), and the presence of microvascular obstruction (p < 0.01). Peak values of both transaminases showed a stronger correlation with CMR parameters than admission values (all p < 0.05). In Kaplan-Meier analysis, a high peak AST or high peak ALT was associated with reduced MACE-free survival (both p < 0.01), whereas admission values were not (both p > 0.05). Peak AST (hazard ratio (HR): 4.93 [1.70-14.32], p = 0.003) and peak ALT (HR: 5.67 [1.94-16.56], p = 0.002) were independent predictors of MACE after adjusting for clinical risk factors. CONCLUSIONS: Transaminases measured in the acute phase after PPCI for STEMI are associated with systolic dysfunction, more extensive myocardial necrosis and microvascular injury with subsequent prognostic information on MACE at long-term follow-up.

RESUMO

Difficulty in attracting live kidney donors may be related to fears regarding both the surgical procedure for kidney harvesting and future failure of the remaining kidney. We conducted a cross-sectional study of households in Maryland to identify public disincentives to living related kidney donation. In multivariate analyses, we assessed the independent effects of several factors on willingness to donate a kidney to a sibling. We also assessed thresholds for factors above which persons would not donate a kidney. Of 385 participants, 66% were extremely willing to donate to a sibling. After adjustment, those who considered the length of a hospital stay, out-of-pocket expenses, size and appearance of a scar, the time it takes to get to the transplant center, and the donor risk of developing kidney failure very important had 50-60% less odds of being extremely willing to donate. Median acceptable levels for risk of complications, hospital stay, compensated and uncompensated time from work, time requiring pain medications, and out-of-pocket expenses were greater than levels from clinical evidence regarding both laparoscopic and open nephrectomy. Unrealistic concerns among the general public regarding live donation may serve as potential disincentives to donation. Efforts to educate the public regarding live donation might help assuage fears and attract those who may not otherwise donate.

RESUMO

Dog bites are commonly associated with soft-tissue injury to the face but rarely result in facial fractures. This article reports six new cases of facial fractures associated with dog bites and reviews additional cases reported in the literature. The demographics of the patients attacked, the location of facial fractures, and the characteristics of associated soft-tissue injuries or complications developing from the dog bite are described. With six new cases and 10 from the literature, this article reviewed a total of 16 cases involving 27 facial fractures. Eighty-seven percent of the cases involved children less than 16 years of age. The periorbital or nasal bones were involved in 69 percent of the cases. Lacerations were the most frequently associated soft-tissue injury. Additional injuries included facial nerve damage, lacrimal duct damage requiring stenting and reconstruction, ptosis from levator transection, and blood loss requiring transfusion. Although facial fractures are not commonly considered to be associated with dog bite injuries, the index of suspicion for a fracture should be raised when the injury occurs in a child, particularly when injury occurs near the orbit, nose, and cheek.
