1.	Björkman, Kristoffer, et al. (författare) Clinical course of patients with single large-scale mtDNA deletions and childhood onset anemia 2022 Ingår i: 14th European Paediatric Neurology Society Congress, Glasgow, UK (ISBN 978-3-00-072065-9). Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract Objective: To add to our knowledge of the clinical spectrum of patients with single large-scale mitochondrial DNA (mtDNA) deletion and childhood onset anemia. Methods: Retrospective collection of clinical data from medical records for patients, both living and deceased, with a single large-scale mtDNA deletion from seven mitochondrial disease centers in five countries. Statistical analysis with descriptive methods and Kaplan-Meier survival analysis. Results: Seventeen patients matching the genetic criterium and with anemia onset before six years of age. Exocrine pancreatic insufficiency was only seen in five patients in this group. Multiple organs were involved in all patients, with the most common non-hematologic ones being skeletal muscle, central nervous system, endocrine, eyes, gastrointestinal system, kidneys, hearing, liver and heart. Psychomotor retardation was seen in ten patients, hearing impairment in nine patients, failure to thrive in eight patients. Eight later developed Kearns-Sayre syndrome. Eleven patients were deceased, with a median age at death of 7.5 years. Conclusions: The classically described phenotype of patients with large-scale mtDNA deletions and early onset anemia is Pearson marrow-pancreas syndrome, characterized by sideroblastic anemia and exocrine pancreas dysfunction. Only a minority of our patients fulfill the original criteria of Pearson syndrome though. Involvement of other organs than the pancreas is more common. The clinical course vary, but multi-system impact is the rule and life-expectancy is low. Early onset anemia in patients with large-scale mtDNA deletions is most frequently not associated with exocrine pancreas dysfunction. Better knowledge of the phenotype is helpful for diagnosis and more accurate prognosis.

(författare) Facing a moral dilemma--introducing a dental care insurance within the public dental service. 2012 Ingår i: Swedish dental journal. - : Swedish dental journal. - 0347-9994. ; 36:3, s. 149-56 Tidskriftsartikel (refereegranskat)abstract Through the reform entitled "Dental care insurance-dental care at a fixed price", patients are offered a dental insurance, a capitation plan, that ensures that they can visit the dentist regularly during a period of three years at a fixed price per month (Frisktandvård).This insurance may be offered to all patients. The aim of this study was to generate a theory explaining the main concern for the staff at the public dental service when they have to introduce and advocate dental care insurance to patients. Interview data from 17 persons, representing different professions within the public dental service, were collected and analyzed simultaneously in line with guidelines for grounded theory. The results indicated that dentists/dental hygienists experienced several difficult standpoints concerning the implementation of the dental insurance, somewhat of a moral dilemma. The staff generally had a "cautiously positive attitude" to the forthcoming dental care insurance, but had perceptions how and when the patients should be offered the insurance and what that may mean to the clinic.The respondents reflected about the economic aspects for the clinic and how the oral health may be affected over time for the patients.
3.	Jonsdottir, Ingibjörg H, 1966, et al. (författare) A pre/post analysis of the impact of the COVID-19 pandemic on the psychosocial work environment and recovery among healthcare workers in a large university hospital in Sweden 2021 Ingår i: Journal of Public Health Research. - : SAGE Publications. - 2279-9028 .- 2279-9036. ; 10:4 Tidskriftsartikel (refereegranskat)abstract Background: The impact of the COVID-19 pandemic on workload, mental health, and well-being of healthcare workers, and particularly those on the front-line, has received considerable attention. Design and methods: We surveyed hospital employees about their working environment during the pandemic and identified departments which were negatively affected in comparison to the pre-pandemic situation, as well as factors contributing to this. Setting and participants We surveyed all hospital employees at Sahlgrenska University Hospital, Sweden in September 2020 and compared results across departments and to the results of a large employee survey from October 2019. Results: The overall impact of the pandemic on perceived working conditions and possibility for recovery differed among departments. During the pandemic, healthcare workers working with COVID-19 patients reported poorer working environments than other employees. Factors significantly related to perception of work environment and recovery during the pandemic included worries of being infected, departmental transfer, and having insufficient access to personal protective equipment. Men reported better working conditions than women in all, but one item and higher age was related to better perceived working environment. Conclusions: Our results indicate that the pandemic differentially affects hospital departments and underscores the multifactorial nature of this topic. Contributing factors to poor perceived working environment could be addressed at times of high workload, such as during the pandemic, including providing appropriate support to managers, ensuring possibility for recovery during working hours, and acknowledging worries about infection. Young healthcare workers and staff who are relocated due to the pandemic warrant special attention.

Sundell, Anna Lena, 1970- (författare) Children with orofacial clefts : dental caries and health-related quality of life 2016 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Background. The current understanding on caries and enamel developmental defects prevalence and frequency, caries risk, health-related quality life (HRQoL) and stress response in young children with cleft lip and/or palate (CL/P) are sparse. In this thesis these aspects were investigated in 5- and 10- year-old children with CL/P in comparison to non-cleft children in the same ages.Design. The studies in this thesis have a cross-sectional case-control design. Participants. The study group consisted of 139 children with CL/P (80 children aged 5 years and 59 aged 10 years) and 313 non-cleft controls (144 children aged 5 years and 169 aged 10 years).Method. Caries was scored according to International Caries Detection and Assessment System (ICDAS II) and developmental enamel defects were measured as presence and frequency of hypoplasia and hypomineralization. Oral hygiene was assessed using Quigley-Hein plaque index. Stimulated saliva samples were analyzed for mutans streptococci, lactobacilli, buffering capacity and secretion rates. Information regarding children’s oral hygiene routines, dietary habits and fluoride exposure were collected with questionnaires. Caries risk was evaluated with algorithm-based software, Cariogram while HRQoL was perceived with KIDSCREEN-52. Stress response was analyzed with cortisol concentration in saliva at three different time points using a commercial competitive radioimmunoassay.Results. Caries prevalence (36% versus 18%) and caries frequency (1.2 dmfs versus 0.9 dmfs) was significantly higher in 5-year-old children with CL/P in comparison to non-cleft controls. In 10-yearolds no significant difference was found between children with CL/P and non-cleft controls in caries prevalence (47% versus 38%) or in caries frequency (0.7 DMFS versus 0.5 DMFS). Children with CL/P had significantly higher prevalence of enamel defects, higher counts of salivary lactobacilli and less good oral hygiene. The odds of being categorized with high caries risk were elevated in children with CL/P. Children with CL/P had similar HRQoL and salivary cortisol concentrations as non-cleft controls. However, 10-year-old boys with CL/P had significantly higher cortisol concentrations in the evening than non-cleft boys.Conclusions. Preschool children with CL/P seem to have more caries in the primary dentition than non-cleft controls. Children with CL/P had increased odds of being categorized as high caries risk individuals compared to controls. Some of the contributing factors seem to be higher prevalence of enamel defects, impaired oral hygiene and elevated salivary lactobacilli. Furthermore, as measured with the help of cortisol concentrations in saliva, children with CL/P were not more stressed than noncleft controls and their HRQoL was comparable to a European norm population. It appears that regular comprehensive preventive oral care in children with CL/P is effective in preventing caries development in permanent teeth. However, children with CL/P are at risk of caries development and preventive oral care should be implemented and started earlier than today.

Wilms, Torben, 1973- (författare) Squamous cell carcinoma of the head and neck, focusing on Epstein-Barr-virus, programmed cell death ligand 1 and serum lipoproteins 2021 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Background: Squamous cell carcinoma of the head and neck (SCCHN)comprises a large group of tumours including the oral cavity and nasopharyngealarea, and typically affects older males in association with alcohol/tobacco usage.Within the oral cavity, the mobile tongue is the most common site for tumourdevelopment. The incidence of squamous cell carcinoma of the oral tongue(SCCOT) is increasing in younger people, which has been suggested to associatewith other than the traditional risk factors for this disease. Two common humanoncogenic viruses, human papillomavirus (HPV) and Epstein-Barr virus (EBV)are connected to certain types of SCCHN, in oropharynx and nasopharynxrespectively. The receptor programmed cell death 1 (PD)-1 and its ligandprogrammed cell death ligand 1 (PD-L1) are particularly relevant in immunecheckpoint control, and elevated levels have been seen in various cancer types. Alink between hyperlipidemia and cancer risk has previously been suggested. Theaim of this thesis was to investigate risk factors and prognostic features forSCCHN, by focusing on EBV, PD-L1 and serum lipoproteins.Materials and methods: Ninety-eight cases of SCCOT and 15 cases of tonsillarsquamous cell carcinoma were examined for the presence of EBV-encodedribonucleic acids (EBERs), EBV deoxyribonucleic acid (DNA) and the proteinEBV-encoded nuclear antigen-1 (EBNA-1), using in situ hybridisation,polymerase chain reaction (PCR) and immunohistochemistry respectively. Onehundred and one cases of SCCOT were examined for expression of PD-L1 intumour and surrounding immune cells using Ventana SP263immunohistochemistry assay and a QuickScore (QS) method. An estimation oftumour-infiltrating immune cells was also performed in 25 of the patients.Circulating levels of PD-L1 were measured using an electrochemiluminescenceassay platform in serum from 30 patients. Finally, serum samples from 106patients and 28 healthy controls were investigated for levels of total cholesterol,low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides andlipoprotein(a).Results: In the first study, using an in situ hybridisation kit no EBER transcriptswere detected. No EBV DNA was identified with PCR analysis, andimmunohistochemistry for EBNA-1 was also negative. In the second study, highertumour cell PD-L1 levels were found in females than males (p = 0.019). Forpatients with low PD-L1 in tumour cells, better survival was shown in males thanfemales (overall survival p = 0.021, disease-free survival p = 0.020). Tumourinfiltrating natural killer (NK) T cells, immature dendritic cells (DCs) and M1macrophages correlated positively with tumour cell PD-L1 (p < 0.05). In the laststudy, the only lipoprotein showing significant difference in concentration iiibetween healthy controls and patients was HDL (p = 0.012). Kaplan-Meiersurvival curves showed that patients with high levels of total cholesterol or LDLhad better survival than patients with normal levels (p = 0.028 and p = 0.007respectively). Adjusting for the effects of age at diagnosis, TNM stage and weightchange, multivariate Cox regression models showed LDL to be an independentprognostic factor for both overall (p = 0.010) and disease-free survival (p =0.018).Conclusion: We excluded EBV as a potential player in SCCOT in both old andyoung patients and highlight the importance of appropriate controls for EBVencoded RNA in-situ hybridization (EBER-ISH) when investigating EBV inhuman diseases. Regarding PD-L1, our data supported the significance of genderon tumour cell PD-L1 expression and demonstrated combined effects of genderand PD-L1 levels on clinical outcome in patients with SCCOT. Data also indicatedthe involvement of specific immune cell types in PD-L1-regulated immuneevasion. Looking at serum lipoproteins, we found high LDL levels to be beneficialfor survival outcome in patients with SCCHN. Furthermore, the use of cholesterollowering medicine for prevention or management of SCCHN needs to be carefullyevaluated.

(författare) Scores of the cleft hearing, appearance and speech questionnaire (CHASQ) in Swedish participants with cleft lip and/or cleft palate and a control population 2021 Ingår i: The Cleft Palate-Craniofacial Journal. - Lawrence : SAGE Publications. - 1055-6656 .- 1545-1569. ; 58:3, s. 347-353 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: The primary aim of this study was to investigate whether there was any difference in scores of the Cleft Hearing, Appearance and Speech Questionnaire (CHASQ) between patients with cleft lip and/or cleft palate (CL/P) and a control population. The second aim was to compare CL/P and control population scores in this study with a British norm CL/P population.DESIGN: Single-site, cross-sectional study with an age-matched control population.SETTING: Participants were recruited from a hospital, a school, and a sports club. They answered the CHASQ in the hospital or at home.PARTICIPANTS: Sixty-four participants with CL/P (7-19 years of age) and a control population of 56 participants without CL/P (9-20 years of age).MAIN OUTCOME MEASURE: CHASQ.RESULTS: There was no statistically significant difference in satisfaction with cleft-related features between the CL/P and the control population. Participants with CL/P were significantly more satisfied with non-cleft-related features than the control population. Cleft Hearing, Appearance and Speech Questionnaire scores were also similar to earlier established British normative data of a CL/P population.CONCLUSION: The results indicated that children and young people with CL/P were as satisfied with their appearance, hearing, and speech as children and young people without CL/P. Swedish CHASQ scores were also similar to British scores.

Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: The primary aim of this study was to compare corresponding scores between 2 existing cleft-specific patient-reported outcome measures (PROMs)-Cleft Hearing Appearance and Speech Questionnaire (CHASQ) and CLEFT-Q. The second aim of the study was to investigate patient opinion on the 2 PROMs.DESIGN: Cross-sectional questionnaire study.SETTING: Participants were recruited from a University Hospital. They answered CHASQ and CLEFT-Q either in the hospital or at home.PARTICIPANTS: Thirty-three participants with cleft lip and/or palate, aged 10 to 19 years.MAIN OUTCOME MEASURE: CHASQ and CLEFT-Q.RESULTS: The CHASQ scores and the corresponding CLEFT-Q scores on appearance correlated significantly. Corresponding scores regarding speech did not correlate significantly. A majority, 15 (58%) participants, answered that they liked CLEFT-Q more than CHASQ, 18 participants (69%) thought CHASQ was easier to complete, and 19 (76%) thought CLEFT-Q would better inform health care professionals.CONCLUSION: Both instruments showed strengths and limitations. Clinicians will have to consider each instrument's respective qualities when choosing to implement either PROM.
9.	Karjalainen, Suvi, et al. (författare) Implementation and evaluation of a teacher intervention program on classroom communication 2020 Ingår i: Logopedics, Phoniatrics, Vocology. - : Taylor & Francis Group. - 1401-5439 .- 1651-2022. ; 45:3, s. 110-122 Tidskriftsartikel (refereegranskat)abstract Background: Media frequently report on overall work-place challenges in Swedish schools, including teachers’ working conditions, their well-being, and students’ declining results. Language is the key to success in every school subject. Therefore, optimal language learning environments are important. Poor sound environments affect teachers’ vocal health, their general well-being, and students’ performance. To provide better conditions for teachers and students, it is necessary to combine optimized room acoustics with other preventive measures such as vocal training and evidence-based tools to improve classroom communication. Teachers play a key role in the classroom and need knowledge and skills in communicative strategies to ensure first-class communication. The purpose of this study is to explore the effects of an intervention program for primary-school teachers comprising strategies for enhanced language learning and interactions in the classroom, with focus on teachers’ verbal and body communication (voice, gaze, and gesture).Methods: Teachers (n = 25) from seven schools teaching in school year 3–6 participated. Assessments were made pre/post intervention and at 5-weeks and 3-months follow-up. The assessments included teachers’ self-assessments (questionnaires) of vocal health, self-efficacy, stress, burnout, and psychosocial work-environment.Results: The main results were significant decrease in voice problems at the 3-months follow-up and significant decrease of both stress and degree of burnout at 5-weeks follow-up. Self-efficacy score had increased significantly at 5-week follow-up.Conclusion: It can be concluded that the intervention program improves teachers’ self-reported vocal health, decreases their perception of stress, and degree of burnout whilst increasing their sense of self-efficacy in classroom management.

Persons with USH1 were recruited through the Swedish Usher database. Totally, 87 adults received the Health on Equal Terms (HET) questionnaire. The HET was adjusted, thus the questions were translated into Swedish sign language, and a large font size, better contrast, and a structure compatible with the Braille script reader were also provided. The questionnaire comprises a wide range of domains related to health and wellbeing. In all, 60 persons responded (60% women, mean age: 49 years, range: 21-79 years). The persons with USH1 were compared to a cross section of the Swedish population that included 5738 individuals (56% women, mean age: 49 years, range: 16-84 years). Significant differences in physical health, psychological health, social trust, and financial situation as well as the odds ratio adjusted for sex and age, and its 95% confidence interval are reported. The psychological health, social trust, and financial situation of persons with USH1 were significantly poorer compared to the reference group although this was not the case for physical health. Persons with USH1 only expressed significantly more problems with headache compared to the cross section of the Swedish population. The respondents revealed major problems with fatigue, loss of confidence, and suicide thoughts and attempts. Major social trust and financial problems were reported in terms of refraining going out alone, not receiving help, having no one with whom to share thoughts, and confide in and being unable to obtain 15.000 SEK (approximately US$1.724 or (sic)1.544) in the case of an unforeseen situation. To identify factors associated with physical health, psychological health, social trust, and financial situation is important in the design of future rehabilitation strategies for persons with USH1. The high level of psychological distress and lack of social trust reported could be related to ontological insecurity, as well as lack of recognition from others. Special attention must be devoted to suicide behavior.

Methods CBT patients, treated with curative intent, completed the EORTC QLQ-C30 and QLQ-H&N35 questionnaires 15 months after diagnosis. The HRQOL of CBT patients was compared to reference scores from the general population and to that of tonsillar carcinoma patients. Results The 190 CBT patients scored significantly worse than members of the general population on most scales. CBT patients with human papilloma virus (HPV)-positive tumors had significantly better HRQOL on 8 of 28 scales than HPV-negative patients. Compared to 405 tonsillar carcinoma patients, CBT patients had significantly worse HRQOL on 8 of the 28 scales, the majority local head and neck related problems. Conclusion One year after treatment, CBT patients' HRQOL was significantly worse in many areas compared to that of the general population and slightly worse than that of tonsillar carcinoma patients.

(författare) Functional Performance Among Active Female Soccer Players After Unilateral Primary Anterior Cruciate Ligament Reconstruction Compared With Knee-Healthy Controls 2017 Ingår i: American Journal of Sports Medicine. - : Sage Publications. - 0363-5465 .- 1552-3365. ; 45:2, s. 377-385 Tidskriftsartikel (refereegranskat)abstract Background: Good functional performance with limb symmetry is believed to be important to minimize the risk of injury after a return to pivoting and contact sports after anterior cruciate ligament reconstruction (ACLR).Purpose: This study aimed to investigate any side-to-side limb differences in functional performance and movement asymmetries in female soccer players with a primary unilateral anterior cruciate ligament (ACL)–reconstructed knee and to compare these players with knee-healthy controls from the same soccer teams.Study Design: Cross-sectional study; Level of evidence, 3.Methods: This study included 77 active female soccer players at a median of 18 months after ACLR (interquartile range [IQR], 14.5 months; range, 7-39 months) and 77 knee-healthy female soccer players. The mean age was 20.1 ± 2.3 years for players with an ACL-reconstructed knee and 19.5 ± 2.2 years for controls. We used a battery of tests to assess postural control (Star Excursion Balance Test) and hop performance (1-legged hop for distance, 5-jump test, and side hop). Movement asymmetries in the lower limbs and trunk were assessed with the drop vertical jump and the tuck jump using 2-dimensional analyses.Results: The reconstructed and uninvolved limbs did not differ in any of the tests. In the 5-jump test, players with an ACL-reconstructed knee performed worse than controls (mean 8.75 ± 1.05 m vs 9.09 ± 0.89 m; P = .034). On the drop vertical jump test, the ACL-reconstructed limb had significantly less knee valgus motion in the frontal plane (median 0.028 m [IQR, 0.049 m] vs 0.045 m [IQR, 0.043 m]; P = .004) and a lower probability of a high knee abduction moment (pKAM) (median 69.2% [IQR, 44.4%] vs 79.8% [IQR, 44.8%]; P = .043) compared with the control players’ matched limb (for leg dominance). Results showed that 9% to 49% of players in both groups performed outside recommended guidelines on the different tests. Only 14 players with an ACL-reconstructed knee (18%) and 15 controls (19%) had results that met the recommended guidelines for all 5 tests (P = .837).Conclusion: The reconstructed and uninvolved limbs did not differ, and players with an ACL-reconstructed knee and controls differed only minimally on the functional performance tests, indicating similar function. It is worth noting that many players with an ACL-reconstructed knee and controls had movement asymmetries and a high pKAM pattern, which have previously been associated with an increased risk for both primary and secondary ACL injury in female athletes.
14.	Broström, Anders, et al. (författare) Factors associated with undiagnosed obstructive sleep apnoea in hypertensive primary care patients 2012 Ingår i: Scandinavian Journal of Primary Health Care. - : Informa Healthcare. - 0281-3432 .- 1502-7724. ; 30:2, s. 107-113 Tidskriftsartikel (refereegranskat)abstract Objective. In hypertensive primary care patients below 65 years of age, (i) to describe the occurrence of undiagnosed obstructive sleep apnoea (OSA), and (ii) to identify the determinants of moderate/severe OSA. Design. Cross-sectional. Setting. Four primary care health centres in Sweden. Patients. 411 consecutive patients (52% women), mean age 57.9 years (SD 5.9 years), with diagnosed and treated hypertension (BP andgt; 140/90). Main outcome measures. Occurrence of OSA as measured by the apnoea hypopnoea index (AHI). Results. Mild (AHI 5-14.9/h) and moderate/severe (AHI andgt; 15/h) OSA were seen among 29% and 30% of the patients, respectively. Comparing those without OSA with those with mild or moderate/severe OSA, no differences were found in blood pressure, pharmacological treatment (anti-hypertensive, anti-depressive, and hypnotics), sleep, insomnia symptoms, daytime sleepiness, or depressive symptoms. Obesity (BMI andgt; 30 kg/m(2)) was seen in 30% and 68% of the patients with mild and moderate/severe OSA, respectively. Male gender, BMI andgt; 30 kg/m(2), snoring, witnessed apnoeas, and sleep duration andgt; 8 hours were determinants of obstructive sleep apnoea. Conclusion. Previously undiagnosed OSA is common among patients with hypertension in primary care. Obesity, snoring, witnessed apnoeas, long sleep duration, and male gender were the best predictors of OSA, even in the absence of daytime sleepiness and depressive symptoms.
15.	Wahlqvist, Moa, 1979- (författare) Health and People with Usher syndrome 2015 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract The present thesis concerns people with Usher syndrome (USH) and their health. People with USH have a congenital hearing loss of various degrees and an eye disease with a progressive course; for some, the balance is also affected. Three clinical groups have been identified 1, 2 and 3, and 13 genes have currently been identified. USH is the most common cause of deafblindness. Clinical knowledge and the limited research that exists have shown that people with deafblindness can experience difficulties in everyday life. Depression, anxiety and social withdrawal have been described.The general aim of the present thesis was to describe the health of people with USH. The empirical material employed was based on an extensive survey in which people with USH answered two questionnaires concerning health, anxiety, depression, social trust, work, health-care, financial situation, and alcohol and drug use. The focus of the present thesis is on general health, physical health and psychological health, social trust and finance. Three studies in the present theses focus on USH1, 2 and 3, respectively; finally, the fourth study provides an in-group comparison of people with USH. The results of studies I and III are compared with a crosssection of the Swedish population. The results revealed poor physical and psychological health, a lack of social trust and a strained financial situation regardless of clinical diagnosis. The discussion stresses the importance of taking a biopsychosocial approach when describing the health of people with USH, in which previous research is lacking. Additional research should focus on the mechanisms at different levels that affect people with USH and their health from a life- course perspective. Furthermore, research should include a salutogenic perspective to explore the resources and strengths of people with USH.
16.	Proceedings from the Second International Interdisciplinary Conference on Perspectives and Limits of Dialogism in Mikhail Bakhtin, 3-5 June, 2009 2010 Proceedings (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract (Preface) This conference focused on the core of Bakhtin’s theory, which concerns dialogue and dialogicality. The conference themes reflected his notion that the “I” and the “self”, the “you” and the “other” are embedded in each other so that each affects the other and as a whole they create a centrifugal force around which communication and life circle. The choice of the two-faced Janus figure as the symbol of the conference reflects the inward and outward aspects of communication’s inherent dialogue and dialogicality. As an ancient Roman god of beginnings and doorways, of the rising and setting sun, looking in opposite directions, Janus has been associated with polarities, that is, seeing different and contrasting aspects and characteristics. As a metaphor it describes Bakhtin’s view on dialogues and dialogicality within or between “selves” and “others”. As a metaphorical symbol it captured the intent, purpose and outcome of the conference as reflected in this collection of papers.

(författare) Inter-rater reliability in classification of canonical babbling status based on canonical babbling ratio in infants with isolated cleft palate randomised to Timing of Primary Surgery for Cleft Palate (TOPS) 2023 Ingår i: Clinical Linguistics & Phonetics. - : Informa UK Limited. - 0269-9206 .- 1464-5076. ; 37:1, s. 77-98 Tidskriftsartikel (refereegranskat)abstract Canonical babbling (CB) is commonly defined as present when at least 15% of all syllables produced are canonical, in other words a canonical babbling ratio (CBR) >= 0.15. However, there is limited knowledge about inter-rater reliability in classification of CB status based on CBR and inter-rater differences in assessment of CBR. We investigated inter-rater reliability of experienced Speech Language Therapists (SLTs) on: classification of CB status based on CBR >= 0.15, CBRs and the total number of syllables per infant used to calculate CBR. Each infant (n = 484) was video-recorded at a clinical site in play interaction with their parent as part of the randomised controlled trial Timing of Primary Surgery for Cleft Palate. Each recording was subsequently assessed by three independent SLTs, from a pool of 29 SLTs. They assessed the recordings in real time. The three assessing SLTs agreed in classification of CB status in 423 (87.4%) infants, with higher complete agreement for canonical (91%; 326/358) than non-canonical (77%; 97/126). The average difference in CBR and total number of syllables identified between the SLT assessments of each infant was 0.12 and 95, respectively. This study provided new evidence that one trained SLT can reliably classify CB status (CBR >= 0.15) in real time when there is clear distinction between the observed CBR and the boundary (0.15); however, when the observed CBR approaches the boundary multiple SLT assessments are beneficial. Thus, we recommend to include assessment of inter-rater reliability, if the purpose is to compare CBR and total syllable count across infants or studies.

(författare) Non-invasive sampling procedure revealing the molecular events at different abutments of bone-anchored hearing systems–A prospective clinical pilot study 2022 Ingår i: Frontiers in Neuroscience. - : Frontiers Media SA. - 1662-4548 .- 1662-453X. ; 16 Tidskriftsartikel (refereegranskat)abstract 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.

(författare) Potential Risk Factors and Prevalence of Voice Symptoms in Students Starting Their Teacher Education 2021 Ingår i: Journal of Voice. - : Elsevier BV. - 0892-1997 .- 1873-4588. ; 35:2, s. 1-323 Tidskriftsartikel (refereegranskat)abstract The aim of the present study was to determine prevalence of voice problems and potential risk factors in teacher students at the start of their education. A total of 1494 students from seven teacher education schools participated in the study. The students answered a questionnaire about 11 risk factors, and one with six questions about voice symptoms, Screen6, and 30 statements in the Voice Handicap Index (VHI). Students reporting at least 2 weekly voice symptoms in Screen6 were assigned to the group with voice problems. Significance level was P < 0.05. Results: prevalence of risk factors was about the same in the seven groups of teacher students except the group with highest proportion of women that also showed the highest proportion of voice problems, 38%. Prevalence of voice problems in the total group was 17%. Comparison of students with or without voice problems showed that all factors except one were more prevalent among students with voice problems and women were overrepresented. Mean total VHI score was 22 in students with voice problems and eight in students without voice problems. Multiple regression analyses showed that frequent throat infections, hearing problems, previous speech therapy, or voice training were the potential risk factors that had the strongest association with voice symptoms as well as with total score in VHI. Conclusions: results from this study show that it is common that teacher students experience voice problems already at the start of their education and potential risk factors associated with voice problems are identified. Knowing that teaching is a high-risk profession for developing voice disorders, it is crucial that teacher students should receive compulsory preprofessional voice education including voice ergonomics and voice training.

Design: A cross-sectional study was conducted and included otoscopy, tympanometry, pure-tone audiometry, and spontaneous otoacoustic emissions (SOAE). A questionnaire was used to evaluate headphone listening habits, tinnitus, and hyperacusis. Study sample: A total of 415 children aged nine years. Results: The prevalence of a hearing threshold20dB HL at one or several frequencies was 53%, and the hearing thresholds at 6 and 8kHz were higher than those at the low and mid frequencies. SOAEs were observed in 35% of the children, and the prevalence of tinnitus was 5.3%. No significant relationship between SOAE and tinnitus was found. Pure-tone audiometry showed poorer hearing thresholds in children with tinnitus and in children who regularly listened with headphones. Conclusion: The present study of hearing, listening habits, and tinnitus in nine-year old children is, to our knowledge, the largest study so far. The main findings were that hearing thresholds in the right ear were poorer in children who used headphones than in children not using them, which could be interpreted as headphone listening may have negative consequences to children's hearing. Children with tinnitus showed poorer hearing thresholds compared to children without tinnitus.

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).

(författare) Variabillity in noise susceptibility in a Swedish population : the role of 35delG mutation in the Connexin 26 (GJB2) gene 2004 Ingår i: Audiological Medicine. - : Informa UK Limited. - 1651-386X .- 1651-3835. ; 2:2, s. 123-130 Tidskriftsartikel (refereegranskat)abstract Although it seems that genetic factors can influence individual susceptibility to noise, still very little is known about the genes or the mechanisms involved. The connexin 26 (Cx26) (GJB2) gene is of particular interest to study in relation to noise, since the gene encodes the gap junction protein Cx26. Noise has a metabolic and mechanical effect on the inner ear and may, therefore, interfere with gap junction channels. In order to investigate whether abnormally high susceptibility to noise induced hearing loss (NIHL) in humans is associated with the common 35delG mutation in the Cx26 gene, 1200 noise‐exposed workers were investigated in Sweden. Using a selection procedure based on audiometric analysis, noise exposure data and questionnaires, noise‐exposed workers were divided into two categories: noise susceptible and noise resistant. There was a correspondence in noise susceptibility between this noise‐exposed population and the international reference ISO Standard 1999. Blood samples were drawn from 245 highly selected male subjects (103 noise susceptible, 112 noise resistant and 30 randomized cases), and genomic DNA was analysed with respect to the Cx26 35delG mutation. The incidence of 35delG carriers among this cohort was determined by multiplex, allele‐specific PCR. Two of the 245 subjects (0.8% ‐ [95% confidence interval 0.1–2.9]) were found to be heterozygous carriers of the 35delG mutation, while the remaining 243 subjects were all non‐carriers. Both the heterozygous carriers were found in the noise susceptible group. Statistical evaluation of the results demonstrated no significant difference in carrier incidence between the noise susceptible and noise resistant individuals in our Swedish noise‐exposed population. In conclusion, there was no support for a major role of Cx26 35delG mutation in explaining the variability in noise susceptibility in this Swedish population.

(författare) The effects of physical exercise and smoking habits on the expression of SPLUNC1 in nasal lavage fluids from allergic rhinitis subjects 2014 Ingår i: International Journal of Pediatric Otorhinolaryngology. - : Elsevier BV. - 0165-5876 .- 1872-8464. ; 78:4, s. 618-622 Tidskriftsartikel (refereegranskat)abstract Objective: Palate lung nasal epithelial clone (PLUNC) is a family of proteins, which are proposed to participate in the innate immune defense against infections in the upper aero-digestive tract. The aim of this study was to investigate the expression of SPLUNC1 in allergic rhinitis subjects with considerations taken to the mucosa( function and smoking habits. Methods: The participants, recruited from a cohort followed from infancy, were re-examined at the age of 18 years regarding allergy development. Based on medical histories and skin prick tests the participants were classified into groups with persistent allergic rhinitis (n = 18), intermittent allergic rhinitis (n = 8) and healthy controls (n = 13). Seven subjects (3, 2 and 2 in each group, respectively) reported smoking habits. The SPLUNC1 levels in nasal lavage fluids were analyzed by Western blot. Changes in the volume of the proper nasal cavity before and after physical exercise (Vol2(increase)) were analyzed by acoustic rhinometiy. Results: Compared to the control group the SPLUNC1 level was significantly lower in the persistent allergy group (3.8 +/- 3.4 OD vs. 1.3 +/- 1.5 OD; p = 0.02), but not in the intermittent allergy group without current exposure to allergens (3.6 +/- 4.7 OD). No differences were found in Vol2(increase) between any of the allergy groups and controls. In smokers Vol2(increase) was significantly reduced (p < 0.01) and the SPLUNC1 levels were lower compared to non-smokers. A significant correlation was found between SPLUNC1 and vol2(increase) (p<0.01; r = 0.53) in non-smokers. Conclusions: Current allergen exposure has an impact on SPLUNC1 expression in nasal lavage fluid, why allergy ought to be considered in study populations where analyses of SPLUNC1 levels are included in the reports. The normal nasal decongestion after exercise was not affected by allergy in contrast to smoking habits. The correlation between SPLUNC1 levels and Vol2(increase) in non-smokers may indicate involvement of SPLUNC1 in the regulation of the normal function of the nasal mucosa. Complementary studies are needed to confirm the smoke-related reduction of SPLUNC1 expression and to analyze the possible participation of SPLUNC1 in the nasal mucosa regulation.

Design: This study is a randomised controlled trial with parallel group design. The research-oriented objectives were evaluated using the Hearing Handicap Inventory for the Elderly (HHIE) and the Communication Strategies Scale (CSS) at baseline and immediately postintervention. Study sample: Selected clients at five different clinics were randomised to an intervention group (n = 78) that took part in online hearing support and a control group (n = 58) that received standard care. Results: The analyses (intention-to-treat) showed statistically significant improvements in the HHIE-total and Emotional subscale scores for the intervention group compared with the control group. The intervention group also showed significantly greater improvement in the CSS-total and Verbal and Nonverbal subscale scores. A subgroup analysis was performed including two groups: HA use and HA use >1 year. A statistically significant improvement was found for the HA users >1 year compared with HA use Conclusions: It is effective to clinically include online hearing support for HA users when addressing self-perceived hearing difficulties and to sharpen communication strategy skills.

The Bone Conduction Implant (BCI) is such a device and has been implanted in 16 patients. The objective of this paper is to give a broad overview of the BCI development to the final results of 13 patients at 5-year follow-up. Follow-up of these patients included audiological performance investigations, questionnaires, as well as safety evaluation and objective functionality testing of the device. Among those audiological measure-ments were sound field warble tone thresholds, speech recognition threshold (SRT), speech recognition score (SRS) and signal to noise ratio threshold (SNR-threshold).The accumulated implant time for all 16 patients was 113 years in February 2022. During this time, no serious adverse events have occurred. The functional improvement for the 13 patients reported in this paper was on average 29.5 dB (average over 0.5, 1, 2 and 4 kHz), while the corresponding effective gain was-12.4 dB. The SRT improvement was 24.5 dB and the SRS improvement was 38.1%, while the aided SNR-threshold was on average -6.4 dB.It was found that the BCI can give effective and safe hearing rehabilitation for patients with conduc-tive and mild-to-moderate mixed hearing loss.

28.	Hua, Håkan, et al. (författare) The impact of different background noises : effects on cognitive performance and perceived disturbance in employees with aided hearing impairment and normal hearing 2014 Ingår i: Journal of the American Academy of Audiology. - : American Academy of Audiology. - 1050-0545 .- 2157-3107. ; 25:9, s. 859-868 Tidskriftsartikel (refereegranskat)abstract Background: Health care professionals frequently meet employees with hearing impairment (HI) who experience difficulties at work. There are indications that the majority of these difficulties might be related to the presence of background noise. Moreover, research has also shown that high-level noise has a more detrimental effect on cognitive performance and self-rated disturbance in individuals with HI than low-level noise.Purpose: The purpose of this study was to examine the impact of different types of background noise on cognitive performance and perceived disturbance (PD) in employees with aided HI and normal hearing.Research Design: A mixed factorial design was conducted to examine the effect of noise in four experimental conditions.Study Sample: A total of 40 participants (21 men and 19 women) were recruited to take part in the study. The study sample consisted of employees with HI (n = 20) and normal hearing (n = 20). The group with HI had a mild-moderate sensorineural HI, and they were all frequent hearing-aid users.Intervention: The current study was conducted by using four general work-related tasks (mental arithmetic, orthographic decoding, phonological decoding, and serial recall) in four different background conditions: (1) quiet, (2) office noise at 56 dBA, (3) daycare noise at 73.5 dBA, and (4) traffic noise at 72.5 dBA. Reaction time and the proportion of correct answers in the working tasks were used as outcome measures of cognitive performance. The Borg CR-10 scale was used to assess PD.Data Collection and Analysis: Data collection occurred on two separate sessions, completed within 4 wk of each other. All tasks and experimental conditions were used in a counterbalanced order. Two-way analysis of variance with repeated measures was performed to analyze the results. To examine interaction effects, pairwise t-tests were used. Pearson correlation coefficients between reaction time and proportion of correct answers, and cognitive performance and PD were also calculated to examine the possible correlation between the different variables.Results: No significant between-group or within-group differences in cognitive performance were observed across the four background conditions. Ratings of PD showed that both groups rated PD according to noise level, where higher noise level generated a higher PD. The present findings also demonstrated that the group with HI was more disturbed by higher than lower levels of noise (i.e., traffic and daycare setting compared with office setting). This pattern was observed consistently throughout four working tasks where the group with HI reported a significantly greater PD in the daycare and traffic settings compared with office noise.Conclusions: The present results demonstrate that background noise does not impair cognitive performance in nonauditory tasks in employees with HI and normal hearing, but that PD is affected to a greater extent in employees with HI during higher levels of background noise exposure. In addition, this study also supports previous studies regarding the detrimental effects that high-level noise has on employees with HI. Therefore, we emphasize the need of both self-rated and cognitive measurements in hearing care and occupational health services for both employees with normal hearing and HI.

(författare) Problems and Life Effects Experienced by Tinnitus Research Study Volunteers : An Exploratory Study Using the ICF Classification 2018 Ingår i: Journal of american academy of audiology. - Reston, VA, United States : American Academy of Audiology. - 1050-0545 .- 2157-3107. ; 29:10, s. 936-947 Tidskriftsartikel (refereegranskat)abstract 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.

(författare) The role of information and instruction to children and parents in homemanagement after tonsil surgery - what is it helpful for them to know? 2010 Konferensbidrag (refereegranskat)abstract OBJECTIVES To create national recommendations for information after tonsil surgery to improve the management ofchildren. METHODS 1. A search of Medline addressing evidence on expectations and advice about medication and nonpharamacological techniques to relieve pain after tonsil surgery and 2. A questionnaire focusing on the routines for information before and after tonsil surgery was administrated to all ENT-clinics in Sweden with 99% response rate. RESULTS There is evidence that information has an empowering effect upon parents to feel more control over their child’s care. Lack of information leads to anxiety and increased perception of pain in the child. Children and parents who were given specific information related to pain and morbidity, reported less pain and were less anxious than those with no or insufficient information. Constructive information should be given gradually, starting preoperatively, to parents and children. A leaflet should contain sufficient information about what happens before, during and is to be expected after surgery, the risks and possible complications, and advice and recommendation of medication and non-pharmacological techniques. Results from the national enquiry (N=48) showed the provision of a variety of different written information from the various clinics, often insufficient. Based on these findings, an information leaflet for patients and a checklist based on the literature for the staff to use at discharge were developed (both will be available). CONCLUSIONS A checklist for the staff insures that parents and children get consistent advice. A leaflet provided before surgery helps children and parents with methods to relieve pain. This could decrease the number of complications and later consultations and give shorter recovery.
31.	Persson, Klara Josefina, et al. (författare) Do best practice recommendations align with current aphasia practices in the Swedish care context : a national survey 2022 Ingår i: Aphasiology. - : Routledge. - 0268-7038 .- 1464-5041. ; 36:8, s. 903-920 Tidskriftsartikel (refereegranskat)abstract Background: For healthcare professionals, decision-makers and taxpayers, clinical guidelines and recommendations are tools for implementing interventions supported by research evidence. To ensure efficient, safe, and equal care for people with aphasia (PWA) in Sweden, it is vital that speech and language pathologists (SLPs) can work in accordance with evidence-based practice.Aim: To investigate to which degree the Best practice recommendations for aphasia (BPRA) are already well aligned with current practice in the management of aphasia and to what extent they would require adjustment to fit the Swedish care contexts.Methods and procedures: The BPRA were translated from English to Swedish according to steps 1 and 2 in the translation method recommended by the World Health Organization (WHO). A web-based questionnaire was used for data collection. All healthcare regions in Sweden were represented, and the study included a total of 109 SLPs. The participants' perceived knowledge and application of the recommendations and whether the recommendations can serve as a basis for national clinical guidelines were summarized quantitatively. The participants' comments on the applicability of the BPRA were analyzed with qualitative content analysis according to an established model.Outcomes and results: Only a few participants indicated they had good knowledge of the BPRA. The responses additionally showed that the application of the BPRA varied between the participants and across clinical settings. Lacking SLP resources was stated to be the main perceived barrier for complying with the recommendations. The participants also stated that the BPRA requires adjustment to provide a partial basis for national clinical guidelines for aphasia and the need for national clinical guidelines to be adjusted to prevalent SLP resources.Conclusions: There are challenges in following up on some of the interventions that, according to both multinational recommendations and Swedish guidelines, should be given priority in the care of PWA. The barriers that are stated to complicate Swedish SLPs' compliance with some of the multinational recommendations are similar to the barriers posed by SLPs in other national studies on the uptake of aphasia rehabilitation recommendations. In Sweden, SLPs experience a lack of resources of various kinds to be able to fully comply with the BPRA.

(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.
33.	Saldert, Charlotta, 1966, et al. (författare) Complexity in measuring outcomes after communication partner training: Alignment between goals of intervention and methods of evaluation 2018 Ingår i: Aphasiology. - : Informa UK Limited. - 0268-7038 .- 1464-5041. ; 32:10, s. 1167-1193 Tidskriftsartikel (refereegranskat)abstract Background: Researchers are currently discussing the need for consensus on a core set of outcome measures to assess interventions in aphasia. For indirect, environmental approaches to aphasia intervention, such as communication partner training (CPT), the roadmap to obtaining consensus on core outcome measures seems especially complex. While the purpose of CPT is to improve communication for people with communication disorders, the intervention is aimed at the communication partner. There is also a variety of goals, activities, and possible settings for CPT. This complexity increases the risk of a mismatch between the goals and content of the intervention and measures used to evaluate the outcome.Aims: The purpose of this paper is to describe the complexity of measuring outcomes from CPT. The aim is to enable clinicians and researchers to reflect on the outcomes to be measured and also on how different types of measures may or may not be aligned with the goals and content of a specific CPT intervention.Main contribution: The current proliferation of outcome measures used in CPT is considered in the light of a survey of general factors to be considered in evaluating intervention outcomes. The complexity of measuring outcomes in CPT is illustrated and the importance of alignment of main objectives, intervention tasks, and projected outcomes is exemplified by referencing two common types of CPT approaches. Objectives relating to knowledge of aphasia, interactional behaviour, and feelings and attitudes are considered in relation to specific outcome measurements. It is suggested that both study-specific and more general measures are needed for capturing and comparing outcomes. The measurement of relevant outcome in CPT is discussed along with implications for future research and clinical practice.Conclusions: Different CPT approaches share the same purpose of facilitating communication in aphasia, but their application in research studies or in the clinic, is specific to the particular context. Special care must thus be taken in both clinical practice and research to safeguard the alignment between objectives, tasks, and projected intervention outcomes and the actual measures used. Further, it is concluded that there is a need for the development of new measures based on a consensus on key outcomes to be measured in CPT.

(författare) National Knowledge-Driven Management of Obstructive Sleep Apnea-The Swedish Approach 2023 Ingår i: Diagnostics. - : MDPI AG. - 2075-4418. ; 13:6 Tidskriftsartikel (refereegranskat)abstract Introduction: This paper describes the development of "Swedish Guidelines for OSA treatment" and the underlying managed care process. The Apnea Hypopnea Index (AHI) is traditionally used as a single parameter for obstructive sleep apnea (OSA) severity classification, although poorly associated with symptomatology and outcome. We instead implement a novel matrix for shared treatment decisions based on available evidence. Methods: A national expert group including medical and dental specialists, nurses, and patient representatives developed the knowledge-driven management model. A Delphi round was performed amongst experts from all Swedish regions (N = 24). Evidence reflecting treatment effects was extracted from systematic reviews, meta-analyses, and randomized clinical trials. Results: The treatment decision in the process includes a matrix with five categories from a "very weak"" to "very strong" indication to treat, and it includes factors with potential influence on outcome, including (A) OSA-related symptoms, (B) cardiometabolic comorbidities, (C) frequency of respiratory events, and (D) age. OSA-related symptoms indicate a strong incitement to treat, whereas the absence of symptoms, age above 65 years, and no or well-controlled comorbidities indicate a weak treatment indication, irrespective of AHI. Conclusions: The novel treatment matrix is based on the effects of treatments rather than the actual frequency of respiratory events during sleep. A nationwide implementation of this matrix is ongoing, and the outcome is monitored in a prospective evaluation by means of the Swedish Sleep Apnea Registry (SESAR).
35.	Bruce, Barbro (författare) Problems of language and communication in children; Identification and intervention 2007 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract This thesis addresses identification and intervention of language and communication problems in children. The issue of identification is addressed in study I by investigating communicative ability in 18-month-old children, and in study II by exploring the prevalence of language and communication problems in children with complex problems, such as attention deficit hyperactivity disorder (ADHD). The issue of intervention is addressed in studies III and IV by analysing verbal interaction in conversations, in which one of the participants is a child with specific language impairment (SLI). Study III explores how dialogues between children with SLI and typically developing peers (TLD) representing the same age (age peers), and the same language level (language peers) respectively, differ with respect to responsiveness, assertiveness and reciprocity. Study IV investigates interactional style and elicitation strategies of speech/language pathologists (SLP) during intervention, and how these factors influence the child with SLI. The results from study I show that receptive skills and symbolic play at 18 months of age are significantly associated with language ability three years later. Study II, in which language skills in children with ADHD were explored, indicates that language ability plays an important role for all other aspects of children's development and behaviour, with the exception of motor skills. Use of language and language comprehension caused these children many more problems than structural aspects of language production. Furthermore, reading and writing problems were found to be very frequent. Study III shows that dialogues between children with SLI and TLD age peers are characterized by more responsiveness and topic coherence than dialogues between children with SLI and TLD language peers. However, the children with SLI were more assertive, i.e., introduced more topics, in dialogues with language peers. Study IV indicates that the children with SLI talked more and had a higher mean length of utterance (MLU) in the free conversational context, whereas the individually selected grammatical targets occurred more often in the training context. In the conversational context the SLPs linked, i.e., attended, more to the child's focus and gave more feedback, while in the training context the individually selected grammatical targets occurred more often and the children were more frequently asked to follow instructions. The results have important clinical implications. First; screening procedures at Child Health Care (CHC) centres should be recommended to focus on receptive language skills and play behaviour, and not only on size of vocabulary at 18 months of age. Second; language skills, in particular language comprehension, language use and literacy skills were found to cause children with ADHD problems, and should therefore be assessed. Third; it is of great value for children with SLI to be in mixed groups with peers representing different ages and language levels, and to avoid the risk of not being selected as playmates. Fourth; increased awareness of how interactional style and elicitation strategies influence the developing language skills in children with SLI can be used in intervention planning, depending on the goals of the specific intervention procedures for the individual child.

(författare) Self-Reported Changes in Cognition, Communication and Swallowing in Multiple Sclerosis: Data from the Swedish Multiple Sclerosis Registry and from a National Survey 2021 Ingår i: Folia Phoniatrica Et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 73:1, s. 50-62 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.

(författare) Detection of subclinical motor speech deficits after presumed low-grade glioma surgery 2023 Ingår i: Brain Sciences. - : MDPI. - 2076-3425. ; 13:12 Tidskriftsartikel (refereegranskat)abstract Motor speech performance was compared before and after surgical resection of presumed low-grade gliomas. This pre- and post-surgery study was conducted on 15 patients (mean age = 41) with low-grade glioma classified based on anatomic features. Repetitions of /pa/, /ta/, /ka/, and /pataka/ recorded before and 3 months after surgery were analyzed regarding rate and regularity. A significant reduction (6 to 5.6 syllables/s) pre- vs. post-surgery was found in the rate for /ka/, which is comparable to the approximate average decline over 10–15 years of natural aging reported previously. For all other syllable types, rates were within normal age-adjusted ranges in both preoperative and postoperative sessions. The decline in /ka/ rate might reflect a subtle reduction in motor speech production, but the effects were not severe. All but one patient continued to perform within normal ranges post-surgery; one performed two standard deviations below age-appropriate norms pre- and post-surgery in all syllable tasks. The patient experienced motor speech difficulties, which may be related to the tumor’s location in an area important for speech. Low-grade glioma may reduce maximum speech-motor performance in individual patients, but larger samples are needed to elucidate how often the effect occurs.

(författare) BMI as a risk factor for the development of chronic rhinosinusitis: a prospective population-based study 2022 Ingår i: European Archives of Oto-Rhino-Laryngology. - : Springer Science and Business Media LLC. - 0937-4477 .- 1434-4726. ; 279, s. 4953-4959 Tidskriftsartikel (refereegranskat)abstract Purpose Obesity is a growing, global health problem and previous cross-sectional studies have demonstrated an association between obesity and chronic rhinosinusitis (CRS). There is, however, a lack of prospective studies regarding the impact of obesity on developing (new-onset) CRS. Methods Questionnaire-based data (n = 5769) relating to new-onset CRS and Body Mass Index (BMI) were collected in 2013 and 2018 from the Telemark population study in Telemark, Norway. Odds ratios for the risk of new-onset CRS in 2018 in relation to BMI in 2013 were calculated, adjusted for smoking habits, asthma, gender and age. Results When comparing the group with normal weight (18.5 <= BMI < 25) with the obese group (BMI >= 30), the odds of new-onset CRS was 53% higher [OR 1.53 (1.11, 2.10)] in the obese group. Conclusion CRS is a multifactorial disease with different phenotypes and it is important to consider obesity when assessing patients with CRS in a clinical setting.

(författare) The plasticity of compensatory eye movements in bilateral vestibular loss : a study with low and high frequency rotatory tests 1989 Ingår i: Acta Oto-Laryngologica. - : Informa UK Limited. - 0001-6489 .- 1651-2251. ; 108:5-6, s. 345-354 Tidskriftsartikel (refereegranskat)abstract Twelve subjects with bilateral vestibular loss, with a mean age of 27 years (18-49) were studied. The loss was based on symptoms of oscillopsia and ice-water caloric tests. Nine subjects were evaluated by low-frequency sinusoidal harmonic acceleration (SHA) rotatory tests (0.01-0.32 Hz), and 3 subjects with high broad-frequency band rotatory tests (0.25-3.25 Hz). During alertness tests (darkness) all subjects had absent or very low gains. When tested with a stationary light in the middle of the swing, the SHA tests showed perfect compensatory eye movements with gains of 1 and phases of approximately 0 degrees. In the broad-frequency test, the gain was near 1 below 1 Hz, decreasing rapidly at higher frequencies. In imaginary stationary target tests (darkness), the gain was enhanced to 'normal' values (0.5) with a phase lead in the low-frequency range (SHA). This could not be replicated in the high-frequency tests. Testing with stationary acoustic guidance (darkness), further enhanced the gain in the SHA tests. A small increase of gain could also be found in the high-frequency tests. Compensatory eye movements, when tested in low-frequency rotatory tests (less than 1 Hz), are to a large extent influenced by non-vestibular mechanisms. By voluntary modifications, normal gains could be produced by patients with 'bilateral vestibular loss'. The phase lead found is proposed to be of central non-vestibular origin. Testing in higher frequency ranges (greater than 1 Hz) could not replicate these findings, thus the broad-frequency band rotatory test should be preferred for adequate vestibular quantification.

Methods The study was based on prospectively collected data regarding hearing and health status in newcomers attending language classes. The examination consisted of pure tone audiometry, an otoscopic examination, and a study-specific questionnaire including questions from the Swedish National Health Survey. Data from the Swedish general population were retrieved from the National Health Survey. Grading of hearing according to the World Health Organization was applied. Results A total of 188 study participants were included in the study. Tinnitus was reported by 38% of the immigrants, and severe tinnitus was reported by 8%. Corresponding percentages from the general population were 17% and 3%. High-frequency hearing loss (PTA(h3) > 25 worse ear) was found to be a significant predictor for tinnitus (p = 0.032, odds ratio (OR): 2.74 [95% confidence interval (CI): 1.40-5.35]). Additionally, self-reported general health significantly predicted tinnitus, with an increased risk of tinnitus relating to worse general health (p < .001, OR: 2.43 [95% CI: 1.66-3.57]). Conclusion Severe tinnitus was more than three times as common in the immigrant participants compared to the Swedish population. High-frequency hearing loss and self-reported worse general health were predictors for tinnitus. Level of Evidence 1b

In the first step, 122 persons received the questionnaire by mail, and 96 (aged 18–84, with a mean age of 55, 53% of whom were female) agreed to participate. The Health on Equal Terms questionnaire was used, which covered such items as health, living conditions, and social relationships. Results for the participants with USH2 were compared to those of a reference group of 5,738 persons who were drawn from a random sample of the Swedish population retrieved from the Swedish Public Health Institute. The odds ratio (adjusted for gender and age), and its 95% confidence interval were calculated.Results: The participants with USH2 reported that their physical and psychological health was significantly poorer than that of the Swedish reference group. They revealed major problems involving headache, fatigue, depression, suicidal thoughts, and suicide attempts. For the male participants, the psychological differences were even more marked than those of the male reference group.Discussion: The identification of factors associated with physical and psychological health and well-being is important for the design of future rehabilitation strategies for people with USH2. Special focus must be placed on the psychological well-being of men with USH2.Implications for practitioners: The management of rehabilitation services for persons with USH2 calls for interdisciplinary teamwork to provide adequate resources to cope with the physical and psychological health issues demonstrated in this study.

(författare) Device abandonment in deafblindness : a scoping review of the intersection of functionality and usability through the International Classification of Functioning, Disability and Health lens 2021 Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 11:1 Forskningsöversikt (refereegranskat)abstract OBJECTIVES: Abandonment of vision, hearing or mobility aids suggests common barriers and facilitators to ongoing device use. However, the possible interactive effects of combined hearing and vision disabilities on device use by those living with deafblindness are unclear. Here we summarise existing knowledge on variables influencing assistive technology use from the perspective of persons living with deafblindness. We used the WHO's International Classification of Functioning, Disability and Health (ICF) framework to contextualise the findings, asking 'What is currently known about variables influencing the (non-)use of assistive devices recommended for persons with deafblindness?'DESIGN: A scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews Checklist.DATA SOURCES: PubMed; ProQuest: ERIC; ProQuest Dissertation; ProQuest: Sociological Thesaurus; Web of Science; Scientific Electronic Library Online; Bielefeld Academic Search Engine; Pascal & Francis; APA PsycINFO and Ebsco for CINAHL were searched through 9 November 2020.ELIGIBILITY CRITERIA: We included peer-reviewed studies that reported on assistive technology, device abandonment/utilisation and provided data from persons living with deafblindness.DATA EXTRACTION AND SYNTHESIS: Four team members independently scored 83 studies for eligibility.RESULTS: Ten articles were chosen for data extraction. The emerging variables replicated established categories of barriers and facilitators: personal, device-related, environmental and intervention variables. The use of the ICF highlighted how an intermediate variable (eg, device acceptability) was necessary in order for a variable to become a barrier or a facilitator to device use.CONCLUSIONS: The variables influencing device use by persons with deafblindness followed the same categories described for single impairments. Usability was challenged in devices that rely on the 'other' sense. Haptic and tactile aids are rarely studied. The limited available information and the dire need for assistive technologies for people with deafblindness emphasises the urgency of research and technology development for this marginalised population.

All rights reserved. Objectives Despite the limited invasiveness of endoscopic transsphenoidal surgery (ETSS), some degree of nasal structure destruction is unavoidable. Our objective was to evaluate sinonasal morbidity and self-reported health before and 6 months after ETSS for pituitary tumors, and to identify possible predictive factors for deterioration in sinonasal health. Design Prospective observational cohort study. Setting University tertiary referral hospital. Participants Totally 109 consecutive adult patients undergoing ETSS for pituitary tumors between 2015 and 2019. Main Outcome Measures Sinonasal symptoms and self-reported health before and 6 months after ETSS, assessed by the Sinonasal Outcome Test (SNOT-22) and the EQ-5D questionnaire. Predictive factors for postoperative deterioration in sinonasal symptoms. Results The overall SNOT-22 score did not change, but the score of the rhinologic domain of SNOT-22 worsened from 6.0 ± 5.9 before to 8.0 ± 7.4 6 months after surgery (p = 0.011). The EQ-5D visual analog scale improved from 64.0 ± 22.9 before to 71.1 ± 18.7 6 months after surgery (p = 0.00088). Univariate and multivariable regression analyses showed that prior sinonasal surgery was associated with a significant worsening in rhinologic symptoms 6 months after surgery (p = 0.046 and p = 0.020, respectively). Conclusions Although self-reported overall health improved, significant deterioration of rhinologic symptoms was seen 6 months after ETSS. This information is important for preoperative patient counselling. Further refinement of the surgical technique and follow-up strategies to reduce postoperative sinonasal morbidity could be of value, especially in patients who have undergone prior sinonasal surgery.

The mode of transmission has been attributed to exhaled droplets, but with the exception of a study on tuberculosis from1968, there is presently almost no scientific evidence ofincreased particle emissions from singing. A substantial number of studies have,however, investigated aerosols emitted from breathing,talking, coughing and sneezing. It has also been shown that justnormal breathing over time can generate more viablevirus aerosol than coughing, since the latter is a less fre-quent activity.Compared to talking, singing often involves continu-ous voicing, higher sound pressure, higher frequencies,deeper breaths, higher peak airflows and more articu-lated consonants. All these factors are likely to increaseexhaled emissions.The aim of this study was to investigate aerosol anddroplet emissions during singing, as compared to talking and breathing. We also examined the presence of SARS-CoV-2 in the air from breathing, talking and singing,and the efficacy of face masks to reduce emissions. In this study we defined aerosol particles as having a drysize in the range 0.5–10mm. Although debatable from anaerosol physics point of view, a cutoff diameter between5 and 10mm is normally used in medicine for classifica-tion of aerosol versus droplet route of transmission. Droplets are here defined as exhaled particles, frommicron size with no upper size limit, and measured dir-ectly at the mouth before complete evaporation, thuspartly in liquid phase.

No randomized treatment study has been performed thus far, and the optimal treatment is not established. Objective The present study aimed to explore various prognostic factors and compare the two main treatments for HNCUP: neck dissection and (chemo) radiation vs primary (chemo) radiation. Methods A national multicenter study was performed with data from the Swedish Head and Neck Cancer Register (SweHNCR) and from the patients' medical records from 2008 to 2012. Results Two-hundred and sixty HNCUP patients were included. The tumors were HPVpositive in 80%. The overall 5-year survival rate of patients treated with curative intent was 71%. Age (p < 0.001), performance status (p = 0.036), and N stage (p = 0.046) were significant factors for overall survival according to the multivariable analysis. Treatment with neck dissection and (chemo) radiation (122 patients) gave an overall 5-year survival of 73%, and treatment with primary (chemo) radiation (87 patients) gave an overall 5-year survival of 71%, with no significant difference in overall or disease-free survival between the 2 groups. Conclusions Age, performance status, and N stage were significant prognostic factors. Treatment with neck dissection and ( chemo) radiation and primary (chemo)

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.

Ca 85 000 svenskar har tinnitus på invalidiserande nivå. Förutom mänskligt lidande orsakar tinnitus samhällskostnader på ca 1.5 miljard kr årligen. Orsaken är till största delen okänd.Vissa tecken tyder på ett samband mellan tinnitus och funktionsstörning i en käkmuskel. Några olika icke–invasiva metoder för mätning av muskelstörning i M Pterygoideus Lateralis har utvärderas. Två av dessa är intressanta för fortsatta studier.Termografi användes för att diagnosticera muskelstörningar på ytligt liggande muskler. Vi såg åtskilliga varma områden på ytliga käk– och nackmuskler på de patienter som hade käkledsstörningar, samt möjligen tecken på onormal värme från M Pterygoideus Lateralis. Mätförhållandena var dock ej ideala.En metod att mäta EMG med adaptiv noise cancelling provades. EMG från en ryggmuskel, stört av en “EKG–signal” från hjärtat användes. Metoden fungerade bra. Fortsatt metodutveckling på t.ex. ryggmuskler borde göras.

The aim of this article is to describe the creation of Comprehensive and Brief ICF Core Sets for Hearing Loss. The core sets consist of the most relevant ICF categories for hearing loss. Method and Results: Four preparatory studies were carried out and presented at a consensus conference, resulting in a Comprehensive ICF Core Set for Hearing Loss, consisting of 117 ICF categories, and a Brief ICF Core Set for Hearing Loss, consisting of 27 categories (of the 117). Conclusion: The Comprehensive ICF Core Set for Hearing Loss can be a user-friendly tool for conducting comprehensive, multidisciplinary assessments. The Brief ICF Core Set can be used for many purposes, such as research and population studies. However, its most common use is by individuals seeking to provide a brief description and assessment of functioning of a person with hearing loss.
