RESUMO
PURPOSE: Equitable representation of children with hearing loss who are members of marginalized or minority groups in behavioral intervention studies enhances inclusivity in the scientific process and generalizability of results. The goal of this systematic review was to ascertain the percentage of studies conducted in the United States in the past 2 decades that reported relevant demographic variables. METHOD: Studies were searched across eight databases and clinical trial registries in October 2022. Variations of the following search strings were used to retrieve peer-reviewed published studies and unpublished clinical trials: children, hearing loss, and intervention. RESULTS: Thirty-nine intervention studies met the inclusion criteria. The selected studies were reviewed and coded for the following demographic variables: area and type of intervention, participant age, hearing technology data, sample size, gender, race/skin color and ethnicity, primary/home language(s), additional disabilities, parental education, family income, and parental occupation. Results revealed that many demographic variables were remarkably underreported, with parental education, family income, and parental occupation variables being the least reported data. CONCLUSIONS: Demographic data can be an important tool for changing disparities related to intervention outcomes. This systematic review suggests that inclusive research practices should be extended to low-literacy or low-economic resources, non-White, and non-English-speaking groups. Inclusion practices coupled with sufficient sample sizes will ultimately aid in identifying hearing health disparities.

Agricultural field experiments are costly and time-consuming, and often struggling to capture spatial and temporal variability. Mechanistic crop growth models offer a solution to understand intricate crop-soil-weather system, aiding farm-level management decisions throughout the growing season. The objective of this study was to calibrate and the Crop Environment Resource Synthesis CERES-Maize (DSSAT v 4.8) model to simulate crop growth, yield, and nitrogen dynamics in a long-term conservation agriculture (CA) based maize system. The model was also used to investigate the relationship between, temperature, nitrate and ammoniacal concentration in soil, and nitrogen uptake by the crop. Additionally, the study explored the impact of contrasting tillage practices and fertilizer nitrogen management options on maize yields. Using field data from 2019 and 2020, the DSSAT-CERES-Maize model was calibrated for plant growth stages, leaf area index-LAI, biomass, and yield. Data from 2021 were used to evaluate the model's performance. The treatments consisted of four nitrogen management options, viz., N0 (without nitrogen), N150 (150 kg N/ha through urea), GS (Green seeker-based urea application) and USG (urea super granules @150kg N/ha) in two contrasting tillage systems, i.e., CA-based zero tillage-ZT and conventional tillage-CT. The model accurately simulated maize cultivar's anthesis and physiological maturity, with observed value falling within 5% of the model's predictions range. LAI predictions by the model aligned well with measured values (RMSE 0.57 and nRMSE 10.33%), with a 14.6% prediction error at 60 days. The simulated grain yields generally matched with measured values (with prediction error ranging from 0 to 3%), except for plots without nitrogen application, where the model overestimated yields by 9-16%. The study also demonstrated the model's ability to accurately capture soil nitrate-N levels (RMSE 12.63 kg/ha and nRMSE 12.84%). The study concludes that the DSSAT-CERES-Maize model accurately assessed the impacts of tillage and nitrogen management practices on maize crop's growth, yield, and soil nitrogen dynamics. By providing reliable simulations during the growing season, this modelling approach can facilitate better planning and more efficient resource management. Future research should focus on expanding the model's capabilities and improving its predictions further.

AIM: (1) To compare the temperature rise in the pulp chamber with different resin materials used for making provisional fixed partial dentures in anterior and posterior region while using Polyvinylsiloxane impression materials as matrix. (2) To identify a superior provisionalization material based on the amount of heat dissipated suitable for anterior and posterior provisional fixed partial denture fabrication. SETTINGS AND DESIGN: Temporary crowns and bridges are integral to Fixed Prosthodontics. It has been observed that conventional fixed prosthesis temporisation materials release heat due to the exothermic polymerisation reaction. When such a provisional material is directly let to set on a vital tooth, the heat transfer causes irreversible changes in the pulp tissue depending of the degree of change. Hence, this study observes amount of heat generation in various materials during temporisation procedure, by simulating similar conditions. MATERIALS AND METHODS: Two Models were fabricated, one simulating missing lateral incisor (Model A) and another simulating missing first molar (Model B). Intact maxillary central incisors and canine for Model A and intact mandibular Second Premolar and Second Molar were selected to act as abutments. These abutment teeth were fitted with the tip of a K-type Thermocouple inside their pulp chambers and these were connected to a digital thermometer. Five temporisation materials were chosen for fabrication of temporary crowns through Direct technique. (1) polymethy methacrylate (Self Cure acrylic), (2) bisacryl composite (Protemp 4), (3) visible light cure urethane dimethacrylate (Revotec LC), (4) barium glass and fumed silica infused methacrylate (Dentsply Integrity) and (5)nano-hybrid composite (VOCO Structur 3). Ten observations were made for each provisional material on each model. During each observation, temperature rise was recorded at 30s interval from the time of application, through the peak and till a decrease in temperature is observed. Polyvinyl siloxane was used as matrix for all except light cure resin, where polypropylene sheet was used. STATISTICAL ANALYSIS USED: Anova test used for statistical. RESULTS: ANOVA test revealed that there was a significant difference in the temperature changes associated with the provisional restorative materials used. Among the five, polymethy methacrylate (self cure resin) showed the maximum rise in temperature, followed by bisacryl composite (Protemp 4), visible light cure urethane dimethacrylate (Revotec LC), barium glass and fumed silica infused methacrylate (Dentsply Integrity) and nano-hybrid composite (VOCO Structur 3). There was no comparable difference between Model A and B but an overall reduction of temperature rise was observed in model B. CONCLUSION: VOCO Structur 3 showed the least temperature rise in the pulp chamber, and overall temperature rise was less for model B which can be attributed to the residual dentin thickness.

Self-eating is a difficult task when hand and finger movements are restricted. Many patients find difficulty in holding utensils because of slender handles. It is essential to have a customized handle that will allow a better grip on traditional feeding aid. When the handle is customized to the patient's hands and fingers, patients will have better control while eating. This reduces their dependency on others, thus helping to regain their lost self-esteem. This technical report describes a simple method of fabricating a three-dimensional (3D)-printed ergonomically designed handle for a feeding aid from materials readily available in the dental office.
RESUMO
OBJECTIVES: To identify the challenges and common issues that the rehabilitation health workforce experienced in delivering services in different practice settings across the world. These experiences could suggest approaches to improving rehabilitation care to people in need. DESIGN: A semi-structured interview protocol centering on 3 broad research questions was conducted to collect data. The data were analyzed to identify common themes across the cohort interviewed. SETTING: Interviews were conducted using Zoom. Interviewees not able to access Zoom provided written responses to the questions. PARTICIPANTS: Participants included 30 key rehabilitation opinion leaders from different disciplines from 24 countries, across world regions and income levels (N=30). INTERVENTIONS: NA. MAIN OUTCOME MEASURES: Although rehabilitation care deficiencies differ in severity, participants reported that the demand for services consistently outstrips available care, regardless of world region or income level. Access and social barriers, particularly in rural areas and remote regions, are common challenges for those delivering and receiving rehabilitation care. RESULTS: Individual voices from the field reported both challenges and hopeful changes in making rehabilitation services available and accessible. CONCLUSIONS: The descriptive approach undertaken has allowed individual voices, rarely included in studies, to be highlighted as meaningful data. Although the research findings are not generalizable beyond the convenience cohort included without further analysis and validation in specific local practice contexts, the authentic voices that spoke out on these issues demonstrated common themes of frustration with the current state of rehabilitation services delivery but also hopefulness that more solutions are on the horizon.

Pain-free dental treatment is important for reducing anxiety, treatment completion, and enhancing acceptance of future dental treatment. Injectable local anesthesia assists this pain-free approach but can cause anxiety in few patients. Achieving proper anesthesia is important to complete the procedure successfully, thereby adding to patient's care and comfort. This article describes a simple technique to manage dental anxiety using virtual reality headset. Audio visual aid helped the patient to relax and eliminate the phobia of local anesthesia injection during surgical tooth extraction. The simple technique enhanced the patient's ability to continue the dental procedure.

For successful management, it is very important to find the cause and plan the treatment accordingly. This article describes a simple step-by-step technique for eliminating the gag reflex in an edentulous patient. This simple approach helped the patient to relax and eliminate the phobia of dental treatment. It also enhanced the patient's ability to continue the dental procedure.
RESUMO
This meta-analysis assessed the efficacy of the Cogmed Working Memory Training program in improving near-transfer measures (verbal and visuospatial working memory) and far-transfer measures (attention, executive function, and academic achievement) in school-age children with and without neurological insults or disorders. Relevant studies were searched in databases and clinical trial registries using the keyword Cogmed. Ten published studies and unpublished data from one study met the inclusion criteria. Hedges g was calculated for each outcome measure obtained at pre-intervention, post-intervention, and 3-6 month time points. Analysis compared outcome measures in the control versus experimental groups and examined the role of moderators on treatment effects (control group intervention, intervention environment). Data revealed significant medium-size effects of the Cogmed program in improving verbal and visuospatial working memory post-intervention and for verbal working memory only at the 3-6 month time point. However, the training did not generalize to the far-transfer measures. Analyses indicated that only the type of intervention provided for the control group moderated treatment effects on verbal and visual working memory. Meta-analytic findings suggest that the Cogmed program leads to short-term improvements and in some cases, long-term improvements in working memory in school-age children; however, these effects may not generalize to far-transfer measures.

Rehabilitation, seen as a disability-specific service needed only by few of the world's population, has not been prioritized in countries and is under-resourced. A rehabilitation-ready health workforce is potentially the most important resource for improving functioning and the quality of life for the 2.41 billion people worldwide needing this care. In April 2019, CGFNS International, Inc., and the Association of Schools Advancing Health Professions (ASAHP) partnered to respond to the World Health Organization's Rehab 2030, which emphasizes the need for global action by professional organizations, development agencies, and civil society to develop and maintain a sustainable workforce for rehabilitation under different healthcare models in different economies. The global certification framework presented in this article provides a mechanism to validate rehabilitation knowledge and practice competence of individual health workers. The impact of certification on upgrading rehabilitation education and upskilling the world's rehabilitation health workforce cannot be overstated.

OBJECTIVE: This study examined the consequences of long-term auditory deprivation on visuospatial functions, visuomotor functions, and visual attention skills in adults with early-onset hearing loss. METHODS: Fifteen adults with bilateral, early-onset (before age 3), severe-to-profound hearing loss who used spoken language participated in this study. Visuospatial (figure ground, form constancy, visual perception) and visuomotor functions (visuomotor integration, visual search) were examined using norm-referenced tests. Visual attention scales were examined using a computerized program, IVA plus continuous performance test. RESULTS: As a group, participants performed in the average range on visuospatial and visuomotor functions when compared to normative data presented in the test instruments. However, participants demonstrated below average performance on sustained visual attention. Duration of cochlear implant use positively correlated with one of the visual attention scales, namely visual speed. CONCLUSIONS: The findings of the current study suggest that adults with early-onset hearing loss may demonstrate difficulties in sustaining attention to visual information. Data also suggest that increased experience with cochlear implant may ameliorate deficits associated with visual attention. Future studies should explore challenges experienced by adults with early-onset hearing loss in their daily activities that may result from this deficit and intervention programs that may enhance visual attention skills.

Accurate detection of mild cognitive impairment (MCI) is important to stratify and address risk. Yet, few short cognitive screening instruments are validated for this. . In Australia, all clients referred to an Aged Care Assessment Team (ACAT) receive comprehensive geriatric assessment (CGA) including the Standardized Mini-Mental State Examination (SMMSE). We compared the accuracy of the quick mild cognitive impairment (Qmci) screen to the SMMSE in 283 participants: 195 with dementia, 47 with MCI, and 41 with subjective cognitive decline (SCD) in an Australian community-based ACAT. Both had similar accuracy in identifying dementia, AUC of 0.86 for the Qmci versus 0.93 for the SMMSE (p = 0.10), but the Qmci was more accurate than the SMMSE in differentiating MCI from SCD, AUC of 0.84 versus 0.71, respectively, p = 0.046. These suggest that the new, short (3-5 min) Qmci screenis appropriate for use in an ACAT or other units conducting CGA.

OBJECTIVE: The objective of the study was to compare visual sequential processing in school-age children with cochlear implants (CIs) and their normal-hearing (NH) peers. Visual sequential processing was examined using both behavioral and an event-related potential (ERP) measures. METHODS: Eighteen children with CIs and nineteen children who had hearing within normal limits (NH) participated in the behavioral study. Subtests from the Test of Visual Perceptual Skills and the Sensory Integration and Praxis Test were administered to all children. ERP measures were collected from five children with CI and five age-matched peers. Peak latencies (N200 and P300) and reaction times for visual sequential processing were compared in these two groups. RESULTS: The findings of the study revealed significant group differences in visual sequential memory and visuo-motor sequencing tasks suggesting that children with severe-profound hearing loss may have difficulties in visual sequential tasks. The study also revealed longer P300 latencies and longer reaction times for a visual sequential matching task in children with CI when compared to their NH peers suggesting slower or delayed processing of visual sequential stimuli. CONCLUSIONS: This exploratory study involving behavioral and ERP measures showed that as a group, children with prelingual, severe-profound hearing loss who use CIs have difficulties with visual sequential processing. These findings may have implications for rehabilitation for children with hearing loss in the light of recent evidence that accurate and efficient processing of sequentially presented visual stimuli is important for language and reading outcomes.

A 61-year-old man presented to a country clinic with involuntary orofacial movements and progressive cognitive decline, causing significant disability and psychosocial distress. Review of records uncovered a 7-year history of presentations to several specialties, including memory clinics, neurology, internal medicine and emergency departments, with varied symptoms, extensive complex work up and inconclusive diagnosis. Comprehensive review at our hospital highlighted inconsistent neurological signs, fluctuating cognition and psychosocial stressors, which preceded symptom onset, leading to the diagnosis of a functional movement disorder (FMD), which subsequently improved with relaxation therapy, cognitive-behavioural therapy and physiotherapy. We illustrate a variety of somatic symptoms, diagnostic clues and management outcomes for FMDs, and the importance of diagnostic criteria to minimise costly, time-consuming and ultimately unnecessary tests of exclusion.

OBJECTIVE: The objective of the study was to examine short-term memory and working memory through both visual and auditory tasks in school-age children with cochlear implants. The relationship between the performance on these cognitive skills and reading as well as language outcomes were examined in these children. METHODS: Ten children between the ages of 7 and 11 years with early-onset bilateral severe-profound hearing loss participated in the study. Auditory and visual short-term memory, auditory and visual working memory subtests and verbal knowledge measures were assessed using the Woodcock Johnson III Tests of Cognitive Abilities, the Wechsler Intelligence Scale for Children-IV Integrated and the Kaufman Assessment Battery for Children II. Reading outcomes were assessed using the Woodcock Reading Mastery Test III. RESULTS: Performance on visual short-term memory and visual working memory measures in children with cochlear implants was within the average range when compared to the normative mean. However, auditory short-term memory and auditory working memory measures were below average when compared to the normative mean. Performance was also below average on all verbal knowledge measures. Regarding reading outcomes, children with cochlear implants scored below average for listening and passage comprehension tasks and these measures were positively correlated to visual short-term memory, visual working memory and auditory short-term memory. Performance on auditory working memory subtests was not related to reading or language outcomes. CONCLUSIONS: The children with cochlear implants in this study demonstrated better performance in visual (spatial) working memory and short-term memory skills than in auditory working memory and auditory short-term memory skills. Significant positive relationships were found between visual working memory and reading outcomes. The results of the study provide support for the idea that WM capacity is modality specific in children with hearing loss. Based on these findings, reading instruction that capitalizes on the strengths in visual short-term memory and working memory is suggested for young children with early-onset hearing loss.

OBJECTIVES: Rehabilitation in the home (RITH) services increasingly provide hospital substitution services. This study examines clinical outcomes in a large metropolitan RITH service in Western Australia. METHODS: The 2010 database of Fremantle Hospital RITH service was interrogated to identify the clinical profile of cases, length of stay (LOS) and clinical outcomes. Negative outcomes included death or unexpected hospital readmission. Multiple logistic regression modelling was used to explore associations with negative outcomes. This study was reviewed by the Institutional Review Board which deemed it not to require ethics approval. RESULTS: There were 1348 cases managed by RITH: 70.6% were aged≥65 years; elective joint replacement (29.7%), medical conditions (20%), stroke (13%), hip fractures (10%) were major contributors. The majority (93.3%) were discharged after a median of 9 days. Negative outcomes occurred in 90 cases (6.7%), including five deaths (0.4%) and 85 readmissions (6.3%). Independent associations with negative outcomes included older age (odds ratio (OR) (95% CI); 1.02, P=0.006), orthopaedic conditions (OR 1.91, P=0.004) and longer inpatient LOS (OR 1.96, P=0.003). Age above 80 years was independently associated with risk of negative outcome (OR 2.99, P=0.004). CONCLUSIONS: RITH had a low rate of negative outcomes. The database proved useful for monitoring quality of service provision. WHAT IS KNOWN ABOUT THE TOPIC?: Rehabilitation in the home environment has proven cost effective for multiple conditions, particularly stroke and elective joint surgery, among others, facilitating better quality of life, with reduced rates of delirium and mortality. Overall there are few negative outcomes and death is rare. WHAT DOES THIS PAPER ADD?: Although RITH services are widely utilised as bed substitution services, there is scant literature on clinical outcomes while within the service. This study focuses on frequency of good and poor clinical outcomes in a well-established RITH service in Western Australia, suggesting pattern recognition of an at-risk cohort by identifying potentially useful predictors of poor outcome. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS?: RITH services are a safe alternative for many, including older people. Health administration databases are useful tools to monitor clinical outcomes. Clinical indicators such as older age, long hospital stay and orthopaedic diagnoses may be useful predictors of poor outcomes in such services.

OBJECTIVE: The objective of the study was to investigate the functions of the vestibular, tactile, visual, and proprioceptive modalities in children with prelinguistic hearing loss. Specifically, the study sought to examine evidence for the compensation hypothesis (auditory deprivation leads to enhancements in functions of other sensory systems) versus the deficiency hypothesis (functions of the spared senses are compromised as a result of auditory deprivation). METHODS: Twelve children between the ages of 5 years, 1 month and 8 years, 11 months with bilateral severe-profound hearing loss participated in the study. All children used bilateral cochlear implants. Subtests of two norm-referenced instruments, the Sensory Integration and Praxis Test and the Beery-Buktenica Developmental Test of Visual-Motor Integration, were administered to all of the children. Mean subtest scores for children with hearing loss were compared with the mean scores for the normative group. RESULTS: As expected, a majority of children demonstrated vestibular dysfunction. Assessment of other modalities revealed significantly below average performance on two tasks by children with hearing loss when compared to the normative group. Both tasks involved temporal processing of tactile or proprioceptive signals. Conversely, children with hearing loss showed significantly better performance compared to the normative group for a spatial task that involved localization of a tactile stimulus. No group differences were found for any of the visual tasks. CONCLUSIONS: Results supported both the compensation and the deficiency hypotheses. The findings have implications for both assessment and intervention of young children with hearing loss. Further investigations are necessary to replicate these findings with a more comprehensive set of measures on a larger cohort of children with prelinguistic, severe-profound hearing loss.

We examined sensory-processing disorder (SPD) in children with cochlear implants and explored the relationship between SPD and duration of hearing loss or duration of cochlear implant use. Caregivers of 30 children completed the Sensory Profile Questionnaire (SPQ). Seventy percent of the children showed "at-risk" or "different" behaviors in one or more of five categories of the SPQ: auditory, visual, vestibular, tactile, and oral processing. No noteworthy relationships surfaced between duration of deafness or duration of cochlear implant use and the atypical behaviors identified. To validate these findings further, postrotary nystagmus (PRN) testing and Miller's Assessment for Preschoolers (MAP) were administered to a subset of children. PRN was atypical in all 6 children tested. MAP findings revealed atypical sensory processing in 4 of the 6 children. Findings suggested that children with cochlear implants may be at risk for SPD. The findings are discussed in light of clinician and teacher referral for occupational therapy evaluations.

PURPOSE: This investigation explored the utility of an acoustic measure, called the discreteness of voicing category (DOVC), in identifying voicing errors in stop consonants produced by children with cochlear implants. Another objective was to examine the perceptual relevance of the DOVC measure and 2 commonly used voice onset time (VOT)-based measures, namely, mean VOT and DeltaVOT (e.g., VOT /t/-VOT /d/). METHOD: Phonetic transcription and acoustic analyses were carried out on syllable-initial /t / and /d/ produced by 10 children with cochlear implants. The DOVC was calculated as the difference between the shortest VOT value of a voiceless stop and the longest VOT value of a voiced stop across several productions of each. RESULTS: Phonetic transcription revealed that 4 of the 10 talkers demonstrated atypical voicing distinctions. Acoustic analyses indicated that the DOVC measure identified these same 4 talkers as producing atypical values, whereas mean VOT and DeltaVOT identified a different set of talkers as demonstrating values outside the normal ranges. CONCLUSION: Preliminary findings suggest that the DOVC measure corresponded with perceptual data better than the other acoustic measures examined in the present study. Data indicate that the DOVC measure may provide perceptually relevant information concerning the production of voicing distinctions.
