- Purpose: To investigate the molecular activities in different compartments around the bone-anchored hearing system (BAHS) with either electropolished or machined abutments and to correlate these activities with clinical and microbiological findings. Materials and methods: Twelve patients received machined or electropolished abutments after implant installation of BAHS. Peri-abutment fluid and tissue were collected from baseline to 12 months. Gene expression of cytokines and factors related to tissue healing and inflammation, regeneration and remodelling, as well as bacterial recognition were determined using quantitative-polymerase chain reaction (qPCR). The clinical status was evaluated using the Holgers scoring system, and bacterial colonisation was investigated by culturing. Results: The gene expression of inflammatory cytokines (IL-8, IL-1β, and IL-10) and bacteria-related Toll-like receptors (2 and 4) was higher in the peri-abutment fluid than at baseline and in the peri-abutment tissue at 3 and 12 months. Conversely, the expression of genes related to tissue regeneration (Coll1a1 and FOXO1) was higher in the tissue samples than in the peri-abutment fluid at 3 and 12 months. Electropolished abutments triggered higher expression of inflammatory cytokines (IL-8 and IL-1β) (in peri-abutment fluid) and regeneration factor FOXO1 (in peri-abutment tissue) than machined abutments. Several cytokine genes in the peri-abutment fluid correlated positively with the detection of aerobes, anaerobes and Staphylococcus species, as well as with high Holger scores. Conclusion: This study provides unprecedented molecular information on the biological processes of BAHS. Despite being apparently healed, the peri-abutment fluid harbours prolonged inflammatory activity in conjunction with the presence of different bacterial species. An electropolished abutment surface appears to be associated with stronger proinflammatory activity than that with a machined surface. The analysis of the peri-abutment fluid deserves further verification as a non-invasive sampling and diagnostic procedure of BAHS.

- Objective: To explore swallowing function and risk factors associated with delayed recovery of swallowing in patients with COVID-19 post–invasive mechanical ventilation using the Functional Oral Intake Scale (FOIS).Design: Longitudinal cohort study.Setting: Three secondary-level hospitals.Participants: Invasively ventilated patients (N=28) who were hospitalized with severe COVID-19 and referred to the hospitals’ speech and language pathology (SLP) departments after mechanical ventilation between March 5 and July 5, 2020 for an evaluation of swallowing function before commencing oral diet.Interventions: SLP assessment, advice, and therapy for dysphagia.Main Outcome Measures: Oral intake levels at baseline and hospital discharge according to the FOIS. Patients were stratified according to FOIS (1-5, dysphagia; 6-7, functional oral intake). Data regarding comorbidities, frailty, intubation and tracheostomy, proning, and SLP evaluation were collected.Results: Dysphagia was found in 71% of the patients at baseline (79% men; age, 61±12y; body mass index, 30±8 kg/m2). The median FOIS score at baseline was 2 (interquartile range [IQR], 1) vs 5 (IQR, 2.5) at hospital discharge. Patients with dysphagia were older (64±8.5y vs 53±16y; P=.019), had a higher incidence of hypertension (70% vs 12%; P=.006), and were ventilated invasively longer (16±7d vs 10±2d; P=.017) or had a tracheostomy (9±9d vs 1±2d; P=.03) longer. A negative association was found between swallowing dysfunction at bedside and days hospitalized (r=–0.471, P=.01), and number of days in the intensive care unit (ICU) (r=–0.48, P=.01).Conclusion: Dysphagia is prevalent in COVID-19 patients after invasive mechanical ventilation and is associated with number of days in hospital and number of days in the ICU. Swallowing function and tolerance of oral diet improved at discharge (P<.001).

- Background: Tinnitus is one of the most distressing hearing-related symptoms. It is often associated with a range of physiological and psychological complications, such as depression, anxiety, and insomnia. Hence, approaching tinnitus from a biopsychological perspective may be more appropriate than from purely a biomedical model.Objective: The present studywas aimed at determining the relationship between tinnitus and the problems and life effects experienced by UK-based tinnitus research study volunteers. Open-ended questions were used. Responses were classified using the International Classification of Functioning, Disability and Health (ICF) framework to understand the impact of tinnitus in a multidimensional manner using a biopsychosocial perspective.Research Design: A cross-sectional survey design was used.Study Sample: Study sample included a sample of 240 adults with tinnitus who were interested in undertaking an Internet-based intervention for tinnitus.Data Collection and Analysis: The data were collated using two open-ended questions. The first focused on problems related to having tinnitus and the second to life effects as a result of tinnitus. Responses were analyzed using a simplified content analysis approach to link concepts to ICF categories in accordance with established linking rules. A Wilcoxon signed-rank test was performed to compare the number of responses between the two questions. The most frequent responses related to body function involved ‘‘emotional functions’’ (b152), ‘‘sleep functions’’ (b134), ‘‘hearing functions’’ (b230), ‘‘sustaining attention’’ (b1400), and ‘‘energy level’’ (b1300). For activity limitations and participation restrictions they were ‘‘communicating with—receiving—spokenmessages’’ (d310), ‘‘socialization’’ (d9205), ‘‘handling stress and other psychological demands’’ (d240), and ‘‘recreation and leisure’’ (d920). The most frequently occurring responses related to environmental factors were ‘‘sound intensity’’ (e2500), ‘‘sound quality’’ (e2501), and ‘‘general products and technology for communication’’ (e1250). ‘‘Coping styles’’ was the most frequently occurring personal factor.Conclusions: The study highlights the use of open-ended questions in gathering useful information about the impact of tinnitus. The responses coded to ICF show that tinnitus impacts many domains, not only particularly body function, but also activity limitations and participation restrictions. The results demonstrate the heterogeneous nature of the impact of tinnitus on people affected.Results: There were 764 responses related to problems identified, 797 responses associated with life effects due to tinnitus, and 37 responses that did not fit into any ICF category. No significant differences were observed in the number of responses between the two questions. In addition, no significant association between the number of responses reported and demographic variables was found. Most of the problems and life effects experienced by tinnitus sufferers were related to body function, followed by activity limitations, and participation restrictions. Only a few responses were related to environmental and personal factors.

Tidskriftsartikel (refereegranskat)abstract
- PurposeKenett et al. (2013) report that the sematic networks, measured by using an oral semantic fluency task, of children with cochlear implants (CI) are less structured compared to the sematic networks of children with typical hearing (TH). This study aims to evaluate if such differences are only evident if children with CI are compared to children with TH matched on chronological age, or also if they are compared to children with TH matched on hearing age.MethodThe performance of a group of children with CI on a verbal fluency task was compared to the performance of a group of chronological-age matched children with TH. Subsequently, computational network analysis was used to compare the semantic network structure of the groups. The same procedure was applied to compare a group of children with CI to a group of hearing-age matched children with TH.ResultsThe children with CI perform on the same level on an oral semantic verbal fluency task as the children with TH matched on hearing age. There are significant differences in terms of the structure of the semantic network between the groups. The magnitude of these differences is very small and they are non-significant for a proportion of nodes included in the bootstrap analysis. This indicates that there is no true difference between the networks. Hearing age, but not age at implantation was found to be significantly positively correlated with semantic verbal fluency performance for the children with CI.ConclusionsThe results from the current study indicate that length of language exposure is an important factor for the structure of the semantic network and the performance on a semantic verbal fluency task for children with CI. Further studies are needed to explore the role of the accessibility of the language input for the development of semantic networks of children with CI.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The aim of this study was to investigate self-reported cognition, speech, communication and swallowing changes in a large sample of individuals with multiple sclerosis (MS) in Sweden. A second aim was to update information about speech and language pathology (SLP) services received by people with MS (pwMS). Method: Self-ratings of cognition, speech/communication and swallowing registered by pwMS between 2012 and 2018 were retrieved from the Swedish MS Registry. In addition, more detailed information about speech, communication, swallowing and provision of SLP services was collected using an online survey distributed via a national patient organization. Results: In total, entries from 5,289 pwMS were retrieved from the MS Registry. Nearly two thirds of the respondents reported that cognition was affected to some degree, whereas approximately one third perceived some difficulties with speech/communication. A smaller group reported swallowing problems. The majority of those who reported problems with speech/communication also reported problems with cognition. Among the 440 individuals who responded to the MS survey, word-finding difficulties were the most frequently self-reported problem related to communication, and the second most common problem was getting off topic. In all, close to four out of five respondents experienced at least one symptom related to speech and communication, such as speech-related fatigue or imprecise articulation. Swallowing difficulties were reported by one out of four respondents in the MS survey. As a result of their speech difficulties, up to one in three experienced changes in professional or social roles and participation. A limited number of respondents had received SLP services, the most common intervention being voice training. Conclusions: In MS, changes associated with cognition as well as speech/communication are frequent, cognitive-linguistic symptoms being the most common. Swallowing difficulties are also relatively prevalent. Access to SLP services seems to be insufficient compared to prevalence of perceived symptoms. Considering that the majority of pwMS are part of the working-age population, access to SLP services must be more highly prioritized and must address cognitive-linguistic problems as well as voice, speech and swallowing dysfunction.

Tidskriftsartikel (refereegranskat)abstract
- Background: Base of tongue cancer incidence and patient survival is increasing why treatment sequelae becomes exceedingly important. Osteoradionecrosis (ORN) is a late adverse effect of radiotherapy and brachytherapy (BT) could be a risk factor. Brachytherapy is used in three out of six health care regions in Sweden. Aims: Investigate if patients treated in regions using BT show an increased risk for ORN and whether brachytherapy has any impact on overall survival. Material and Methods: We used data from the Swedish Head and Neck Cancer Register between 2008–2014. Due to the nonrandomized nature of the study and possible selection bias we compared the risk for ORN in brachy vs non-brachy regions. Results: Fifty out of 505 patients (9.9%) developed ORN; eight of these were treated in nonbrachy regions (16%), while 42 (84%) were treated in brachy regions. Neither age, sex, TNM-classification/stage, p16, smoking, neck dissection, or chemotherapy differed between ORN and no-ORN patients. The risk for ORN was significantly higher for patients treated in brachy regions compared to non-brachy regions (HR = 2,63, p =.012), whereas overall survival did not differ (HR = 0.95, p =.782). Conclusions and Significance: Brachytherapy ought to be used cautiously for selected patients or within prospective randomized studies.

- Objective: Examine deaf and hard of hearing (DHH) children's phonological processing skills in relation to a reference group of children with normal hearing (NH) at two baselines pre intervention. Study the effects of computer-assisted phoneme-grapheme correspondence training in the children. Specifically analyze possible effects on DHH children's phonological processing skills.Methods: The study included 48 children who participated in a computer-assisted intervention study, which focuses on phoneme-grapheme correspondence. Children were 5, 6, and 7 years of age. There were 32 DHH children using cochlear implants (CI) or hearing aids (HA), or both in combination, and 16 children with NH. The study had a quasi-experimental design with three test occasions separated in time by four weeks; baseline 1 and 2 pre intervention, and 3 post intervention. Children performed tasks measuring lexical access, phonological processing, and letter knowledge. All children were asked to practice ten minutes per day at home supported by their parents.Results: NH children outperformed DHH children on the majority of tasks. All children improved their accuracy in phoneme-grapheme correspondence and output phonology as a function of the computer-assisted intervention. For the whole group of children, and specifically for children with CI, a lower initial phonological composite score was associated with a larger phonological change between baseline 2 and post intervention. Finally, 18 DHH children, whereof 11 children with CI, showed specific intervention effects on their phonological processing skills, and strong effect sizes for their improved accuracy of phoneme-grapheme correspondence.Conclusion: For some DHH children phonological processing skills are boosted relatively more by phoneme-grapheme correspondence training. This reflects the reciprocal relationship between phonological change and exposure to and manipulations of letters.

Tidskriftsartikel (refereegranskat)abstract
- Objectives. Reduced respiratory function following lower cervical spinal cord injuries (CSCIs) may indirectly result in vocal dysfunction. Although self-reports indicate voice change and limitations following CSCI, earlier efforts using global perceptual ratings to distinguish speakers with CSCI from noninjured speakers have not been very successful. We investigate the use of an audience response system-based approach to distinguish speakers with CSCI from noninjured speakers, and explore whether specific vocal traits can be identified as characteristic for speakers with CSCI. Methods. Fourteen speech-language pathologists participated in a web-based perceptual task, where their overt reactions to vocal dysfunction were registered during the continuous playback of recordings of 36 speakers (18 with CSCI, and 18 matched controls). Dysphonic events were identified through manual perceptual analysis, to allow the exploration of connections between dysphonic events and listener reactions. Results. More dysphonic events, and more listener reactions, were registered for speakers with CSCI than for noninjured speakers. Strain (particularly in phrase-final position) and creak (particularly in nonphrase-final position) distinguish speakers with CSCI from noninjured speakers. Conclusions. For the identification of intermittent and subtle signs of vocal dysfunction, an approach where the temporal distribution of symptoms is registered offers a viable means to distinguish speakers affected by voice dysfunction from non-affected speakers. In speakers with CSCI, clinicians should listen for presence of final strain and nonfinal creak, and pay attention to self-reported voice function and voice problems, to identify individuals in need for clinical assessment and intervention.

- OBJECTIVES/HYPOTHESIS: To study longitudinal prevalence of otitis media with effusion (OME) in children between 7 and 16 years of age by cleft group, and hearing sensitivity across time and across frequencies. STUDY DESIGN: Retrospective and longitudinal. METHODS: All children with cleft palate born from 1991 to 1993 were included in the study (n = 58). Audiological and otological data were reviewed at 7, 10, 13, and 16 years of age. The group was divided by cleft type (24 unilateral cleft lip and palate, 23 cleft palate only, and 11 bilateral cleft lip and palate). RESULTS: The prevalence of abnormal middle ear status decreased significantly with age. When comparing cleft types, the isolated cleft palate group presented with a significantly lower prevalence of abnormal middle ear status than the other groups at 7 and 16 years of age (21% as compared to 32% in the unilateral group and 38% in the bilateral group). The pure-tone average improved with age, while the high-frequency pure-tone average did not. When cleft types were compared, the bilateral group demonstrated significantly poorer hearing in the high frequencies than the other groups. CONCLUSION: Children with cleft palate need regular audiological and otological follow-up to ensure management is appropriate and timely. The increased hearing thresholds in the high frequencies may be due to the increased episodes of OME.

Tidskriftsartikel (refereegranskat)abstract
- Two previous studies suggest that cigarette smoking reduces acoustic neuroma risk; however, an association between use of snuff tobacco and acoustic neuroma has not been investigated previously. The authors conducted a case-control study in Sweden from 2002 to 2007, in which 451 cases and 710 population-based controls completed questionnaires. Cases and controls were matched on gender, region, and age within 5 years. The authors estimated odds ratios using conditional logistic regression analyses, adjusted for education and tobacco use (snuff use in the smoking analysis and smoking in the snuff analysis). The risk of acoustic neuroma was greatly reduced in male current smokers (odds ratio (OR) = 0.41, 95% confidence interval (CI): 0.23, 0.74) and moderately reduced in female current smokers (OR = 0.70, 95% CI: 0.40, 1.23). In contrast, current snuff use among males was not associated with risk of acoustic neuroma (OR = 0.94, 95% CI: 0.57, 1.55). The authors' findings are consistent with previous reports of lower acoustic neuroma risk among current cigarette smokers than among never smokers. The absence of an association between snuff use and acoustic neuroma suggests that some constituent of tobacco smoke other than nicotine may confer protection against acoustic neuroma.
