Psychological and social difficulties in young non-help-seeking adolescents at risk for psychosis: insights from a large cohort study.

Background: This study used data from the Norwegian Mother, Father, and Child Cohort Study (MoBa), and explored the psychological and social challenges of 14-year-olds who report psychotic symptoms. Research on help-seeking youths indicates comorbid symptoms of depression, anxiety, and social deterioration, but less is known about non-help-seeking individuals who may not use healthcare services, possibly skewing comorbidity profiles. Also, findings suggest that adolescents manifesting psychotic symptoms refrain from pursuing help. This gap underscores the necessity of studying non-help-seeking adolescents to better understand their needs and the risks they face without intervention. Methods: We analyzed responses from adolescents who completed the 14-year questionnaire in MoBa (N = 127), identifying those as at risk by their high scores on psychosis-risk items, within the top 0.4% (N = 58). Comparative analyses were conducted against matched controls to assess differences in psychological and social functioning (N = 69). Results: Results indicated that the at-risk adolescents experience significantly more depression and anxiety and have lower self-esteem and poorer social functioning than controls. Social functioning parameters, including leisure activities, social competence, quality of parental relationship, and sense of school belonging, were significantly worse than those observed in controls. The results indicate a pronounced vulnerability among non-help-seeking adolescents at-risk, similar to issues seen in help-seeking youths. Conclusion: These findings highlight the importance of early identification and intervention strategies that reach beyond traditional clinical settings, suggesting the efficacy of population or community-based screenings to prevent long-term adverse outcomes. The study proposes a broader understanding of psychosis risk, stressing the importance of inclusive approaches to support at-risk adolescents effectively.

Behind the Headset: Predictive Accuracy of Patient-Reported Outcome Measures for Voice Symptoms in Call Centers.

Objective: This study examines factors predicting self-reported voice symptoms in call center workers. Methods: Multivariate analysis and predictive modeling assess personal, work-related, acoustic, and behavioral factors. Generalized Linear Models (GLMs) and Receiver Operating Characteristic (ROC) curves are employed. Results: Age and sleep patterns impacted voice quality and effort, while workplace factors influenced symptom perception. Unhealthy vocal behaviors related to tense voice and increased effort, while hydration was protective. Voice acoustics showed diagnostic potential, supported by ROC data. These findings emphasize voice symptom complexity in call center professionals, necessitating comprehensive assessment. Limitations: This study recognizes its limitations, including a moderate-sized convenience sample and reliance on PROM metrics. Future research should incorporate more objective measures in addition to self-reports and acoustic analysis. Value: This research provides novel insights into the interplay of personal, occupational, and voice-related factors in developing voice symptoms among call center workers. Predictive modeling enhances risk assessment and understanding of individual susceptibility to voice disorders. Conclusion: Results show associations between various factors and self-reported voice symptoms. Protective factors include sleeping more than six hours and consistent hydration, whereas risk factors include working conditions, such as location and behaviors like smoking. Diagnostic models indicate good accuracy for some voice symptom PROMs, emphasizing the need for comprehensive models considering work factors, vocal behaviors, and acoustic parameters to understand voice issues complexity.

Objetivo: Este estudio examina los factores que predicen los síntomas de voz en los trabajadores de call centers. Métodos: Se utilizan análisis multivariados y modelos predictivos para evaluar factores personales, laborales, acústicos y de comportamiento. Se emplean Modelos Lineales Generalizados (GLM) y curvas ROC. Resultados: La edad y los patrones de sueño afectaron la calidad vocal y el esfuerzo, mientras que los factores laborales influyeron en la percepción de síntomas. Los comportamientos vocales no saludables se relacionaron con voz tensa y mayor esfuerzo, mientras que la hidratación fue protectora. Los parámetros acústicos de voz mostraron potencial diagnóstico respaldado por datos de ROC. Los hallazgos subrayan complejidad de síntomas vocales en profesionales de centros de llamadas, requiriendo una evaluación integral. Limitaciones: Este estudio reconoce sus limitaciones, que incluyen una muestra de conveniencia de tamaño moderado y la dependencia de medidas PROMs. Futuras investigaciones deberían incorporar medidas objetivas, además de los autorreportes y análisis acústico. Importancia: Esta investigación aporta nuevos conocimientos sobre factores personales, laborales y síntomas de voz en trabajadores de call centers. El modelado predictivo mejora la evaluación de riesgos y la comprensión de la susceptibilidad individual a trastornos de la voz. Conclusión: Los resultados muestran asociaciones entre diversos factores y los síntomas vocales reportados. Los factores de protección incluyen dormir más de seis horas y una hidratación constante; los factores de riesgo incluyen las condiciones de trabajo, como la ubicación y comportamientos como fumar. Los modelos de diagnóstico indican una buena precisión para algunas PROMs de síntomas de la voz, lo que subraya la necesidad de modelos integrales que tengan en cuenta los factores laborales, los comportamientos vocales y los parámetros acústicos para comprender la complejidad de los problemas de la voz.

Utilisation of a think-aloud protocol to validate a self-reported periodontitis questionnaire.

OBJECTIVES: The gold standard approach to diagnose periodontitis is based on clinical examination and radiographic investigations. This, however, is expensive, tedious, and not feasible in population-level assessments. The self-reported periodontitis questionnaire offers great benefit to facilitate larger epidemiological surveys. There is limited evidence on cognitive validation of self-reported periodontitis questionnaire. This study employed a think aloud approach to investigate if participants interpreted, comprehended, and understood the items in a self-reported periodontitis questionnaire, in the same way as researchers' intended. METHODS: 20 adults, resident of the UK and fluent in English participated in online recorded think aloud interviews. The self-reported periodontitis questionnaire consists of 15 questions and 2 open ended questions. The interviews were then transcribed and coded by two independent researchers according to predefined categories representing comprehension and conventional content analysis was used to analyse open-ended data. RESULTS: The think aloud approach revealed that most of the questions in the self-reported periodontitis questionnaire were well understood by the participants. Two items, however, were identified as problematic: one was misinterpreted, and another question was not understood by most of the participants. Qualitative conventional content analysis of open-ended questions reiterated and complemented the findings of the think aloud study. Further questions coded as problematic for 3 or more participants were then considered for rephrasing. CONCLUSIONS: This study revealed the interpretation and understanding of self-reported periodontitis questions by English speaking UK residents and highlighted the probable reason for lower sensitivity values of the self-reported periodontitis questionnaire. CLINICAL SIGNIFICANCE: This study employed think-aloud approach to capture the thought process of the participants as they answered questions on self-reported periodontitis questionnaire. Overall, the questionnaire was well received by the participants, however, some questions were misunderstood/misinterpreted. This study highlights the potential information bias if participants do not understand the questions in epidemiological surveys.

Prevalence of self-reported voice and swallowing complaints in an outpatient geriatric population.

Background: Older adults suffer from increased rates of dysphagia and dysphonia, both of which have a profound effect on quality of life and are often underdiagnosed. We sought to better understand the prevalence of these complaints and the potential utility of a patient-reported screening program in a geriatrics clinic. Methods: Using an IRB-approved cross-sectional survey and retrospective cohort design, we recruited participants from a population of new patients seeking care at an academic geriatrics clinic. We used three validated questionnaires to assess self-reported dysphagia, dysphonia, and pill dysphagia: the Eating-Assessment Tool-10 (EAT-10), the Voice Handicap Index-10 (VHI-10), and the PILL-5. Patients who screened positive on any questionnaire were offered referral to a laryngologist for additional evaluation. Patients who screened positive on the PILL-5 were also offered referral to our geriatric pharmacist. Results: Among our 300 patients surveyed, the mean age was 76 (SD 8.46). A total of 82 (27.3%) patients screened positive (73 on EAT-10, 10 on PILL-5, 13 on VHI-10) and were offered referral, of which 36 accepted. These positive screening patients took more prescription medications (p = .024) and had a higher GDS score (p < .001) when compared to the patients who screened negative. Conclusions: Many new patients seeking generalized care at our center screened positively for dysphagia and/or dysphonia on validated questionnaires. Geriatric patients may benefit from integrating screening for these disorders to identify the need of further evaluation. It is unknown if these survey tools are appropriate in a non-otolaryngology clinic. Level of evidence: III.

Longitudinal tracking of alcohol expectancies and their associations with impulsivity in alcohol naïve youth in the adolescent brain cognitive development (ABCD) study.

Background: Positive and negative alcohol expectancies (PAEs and NAEs, respectively) and impulsivity are key risk factors for the onset of alcohol use. While both factors independently contribute to alcohol initiation, the developmental aspects of AEs and their nuanced relationship with impulsivity are not adequately understood. Understanding these relationships is imperative for developing targeted interventions to prevent or delay alcohol use onset in youth. Methods: This study utilized the Adolescent Brain Cognitive Development cohort to examine how PAEs and NAEs develop over time and relate to each other. We also explored how self-reported and behavioral impulsivity at baseline (~10 years old) are associated with the longitudinal development of PAEs and NAEs in youth Ages 11, 12, and 13 (n = 7493; 7500; and 6981, respectively), as well as their time-specific relationships. Results: Findings revealed while PAEs increased steadily over all three years, NAEs increased from ages 11-12 and then remained unchanged between 12 and 13. Overall, PAEs and NAEs were inversely related. Moreover, PAEs positively correlated with sensation seeking and lack of premeditation, while NAEs negatively correlated with positive urgency. Interestingly, a time-specific association was observed with PAEs and lack of perseverance, with a stronger correlation to PAEs at Age 11 compared to Age 12. Conclusions: Overall, this study provides valuable insights into the divergent developmental trajectory of PAEs and NAEs, and their overall and time-specific associations with impulsivity. These findings may guide focused and time-sensitive prevention and intervention initiatives, aiming to modify AEs and reduce underage drinking.

Low back pain characteristics in adolescent patients with early-stage spondylolysis: a prospective study.

PURPOSE: Early-stage spondylolysis (ESS) is a common cause of acute low back pain (LBP) in adolescents. When treating patients with ESS, early diagnosis is essential, yet difficult without magnetic resonance imaging. This study evaluates a self-reported questionnaire for detecting ESS. METHODS: We evaluated a total of 69 adolescents (≤ 18 years old) with acute LBP (≤ 1 month) with plain radiography, magnetic resonance imaging and a questionnaire including the following parameters: exercise frequency per week, daily training time, the necessity for stopping sports activity, pain-producing situations, pain quality, pain response to hyperextension or hyperflexion, pain location, and pain extent. Patients with obvious pathological findings other than ESS (e.g., disk herniation or infection) were excluded. The correlation of each question and gender, regarding ESS was determined, to evaluate the value of the originally developed questionnaire. RESULTS: 24 out of 69 patients were diagnosed with ESS (ESS group), with a mean age of 13.9 years old and 21 males and 3 females in the group. 45 patients had NS-LBP, with a mean age of 14.6 years old, and 28 males and 17 females in the group. Correlation analyses showed weak associations between ESS and higher frequency of exercise per week, longer training time per day, and pain-producing situations. There was also a moderate association between ESS and male gender. CONCLUSION: Exercise frequency, training time, pain-provoking situations, and gender could be important factors to detect ESS within this questionnaire.

Self-reported health, function, and use of health care services in older prostate cancer survivors compared to matched controls: a cross-sectional study.

PURPOSE: Information about outcomes of particular relevance to older prostate cancer survivors is limited. This study aimed to compare health, activities of daily living (ADL), and use of health care services between survivors and matched controls. METHODS: A single-centre study on men treated for prostate cancer with curative intent at the age ≥ 70 years 2 to 7 years earlier. Controls matched on age and education were drawn (1:3) from the Trøndelag Health Study (HUNT) in Norway. Self-reported general health, independence in ADL and instrumental activities of daily living (IADL), hospital admissions and emergency room visits were compared by estimating non-adjusted and adjusted (age, education, comorbidity, cohabitant status and pack years of smoking) regression models. RESULTS: The majority of both survivors (N = 233) and controls (N = 699) reported good (58.7% vs. 62.7%) or very good (11.2% vs. 6.8%) health and independence in ADL (95.6% vs. 96.3%) and IADL (82.7% vs. 81.9%). Hospital admission was reported by 17.3% vs. 18.2% and emergency room visit by 23.6% vs. 26.7%. Regression models showed no significant differences between survivors and controls. CONCLUSIONS: Older prostate cancer survivors reported similar health, independence in ADL and use of emergency room and hospital admissions as matched controls. IMPLICATIONS FOR CANCER SURVIVORS: This study shows that survivors after curatively intended treatment of prostate cancer have as good health as matched controls, indicating that many patients tolerate such treatment well despite being of old age and that current practice for selection of patients offered such treatment is appropriate.

Self-reported exposure to blood and body fluids and serological evidence of lifetime exposure to hepatitis B virus among health care workers in Ghana: a cross-sectional study.

INTRODUCTION: In Sub-Saharan Africa alone, about 40-65% of Hepatitis B Virus infections among HCWs were a result of percutaneous occupational exposures to contaminated blood and body fluids of patients. Occupational exposure to blood and body fluids among healthcare workers is on the rise in Ghana. However, the relationship between self-reported exposures to blood and body fluids suspected to be contaminated with the hepatitis B virus and actual serological evidence of exposure remains unknown. The aim of the study however was to assess the self-reported exposure to HBV as against the serological evidence of lifetime exposure to HBV and associated factors among Ghanaian HCWs. METHODS: The study was a cross-sectional analytical survey that involved 340 HCWs who were recruited using a simple random sampling procedure from six cadres of staff from five districts in Greater Accra. The participants were surveyed using a validated instrument and 5mls of venous blood was aseptically withdrawn for qualitative detection of Anti-HBc. SPSS version 23.0 was used to analyze the data to obtain proportions, odds ratios and their corresponding confidence intervals with the level of significance set at 0.05. RESULTS: The response rate was 94% with Nurses and Doctors in the majority with a mean age of 35.6 ± 7.2. Self-reported exposure to HBV was 63% whereas lifetime exposure to HBV (Anti-HBc) prevalence was 8.2% (95% CI = 5.0-11.0%). Females were 60% less likely to be exposed to HBV (aOR = 0.4; 95% CI = 0.1-0.9) than their male counterparts. HCWs without training in the prevention of blood-borne infections had almost three times higher odds of being exposed to HBV in their lifetime (aOR = 2.6; 95% CI = 1.0-6.4). CONCLUSIONS: The findings of this study suggest that self-reported exposure to HBV-contaminated biological materials was high with a corresponding high lifetime exposure to HBV. The female gender was protective of anti-HBc acquisition. Apart from direct interventions for preventing occupational exposures to HBV in the healthcare setting, periodic training of all categories of healthcare workers in infection prevention techniques could significantly reduce exposure to the Hepatitis B virus.

Hand fatigability, self-reported fatigue, and functionality in individuals with multiple sclerosis: A cross-sectional study.

BACKGROUND: The individual experience of fatigue and fatigability in individuals with Multiple Sclerosis (MS) can vary greatly, beyond the high prevalence of fatigue in MS. Although fatigue is known as a common symptom that affects and potentially limits individuals with MS, it has recently been determined that fatigability also causes consequences that limit individuals' daily lives. The purpose of this study was to compare the associations between self-reported levels of fatigue, measured fatigability, and estimates of functional capacity in people with MS and sex- and age-matched healthy individuals. METHODS: Twenty-three individuals with Relapsing-Remitting MS (RRMS) diagnosis and 23 age- and sex-matched healthy individuals were included in the study. To examine the fatigability level Dynamic and Static Fatigue Index were used for gross and pinch-grip, and manual dexterity and functionality levels the Scale for the Assessment and Rating of Ataxia (SARA), Nine Hole Peg Test (NHPT), and Dexterity Questionnaire-24 (DextQ-24) were used. While the Fatigue Severity Scale (FSS) and Fatigue Impact Scale (FIS) were used to examine self-reported fatigue, the Beck Depression Inventory (BDI) was used to assess emotional status. RESULTS: There was no difference between RRMS and healthy individuals in terms of fatigability levels (p > 0.05). While the relationship between Static and Dynamic Fatigue Index gross grip fatigability and FSS and FIS was not found to be statistically significant, the relationship between non-dominant side pinch grip Static Fatigue Index and FSS and FIS was significant. In addition, the relationship between the non-dominant side gross grip Static Fatigue Index and the DextQ-24 dressing and daily activities subsections, and the dominant side pinch grip Dynamic Fatigue Index and the television/compact disk/digital video disk subsection of DextQ-24 was significant (p < 0.05). CONCLUSION: Fatigability was related to daily life upper limb use for gross grip and self-reported fatigue for pinch grip in individuals with RRMS. It was concluded that future studies focusing on hand fatigability could also consider manual dexterity and self-reported fatigue in individuals with MS from the early-stage. Clarifying the relationship of between fatigability and self-reported fatigue to functioning will allow clinicians to plan more appropriate and directed treatment approaches for individuals with RRMS. TRIAL REGISTRATION: ClinicalTrials.gov NCT05880745.

Adaptation and Validation of the Sydney Swallow Questionnaire into Kannada (KSSQ).

Self-rating questionnaires are necessary to quantify the impairment and the impact of impairment on the quality of life, provided that these questionnaires are delivered in the patient's native language. There are no questionnaires to assess the symptom severity of oropharyngeal dysphagia in Kannada-speaking individuals. The Sydney Swallow Questionnaire (SSQ) is one such explicit tool to assess the symptoms of dysphagia, especially among patients with oropharyngeal dysphagia. The SSQ is a simple and easy-to-understand questionnaire. Therefore, the present study aimed to adapt and validate the SSQ in Kannada. English version of the SSQ was translated to Kannada and was administered to two groups of native Kannada-speaking participants - Group 1 included 53 participants (66.49 + 12.65 years) diagnosed with oropharyngeal dysphagia, and Group 2 included 53 age and gender-matched native Kannada speakers with normal swallowing ability with no history and symptoms of swallowing disorders. Cronbach's alpha was used to assess the test-retest reliability. Internal consistency was assessed using the split-half correlation. The concurrent validity of the Kannada version of SSQ (KSSQ) was measured by determining the correlation between the total scores of KSSQ and the Kannada version of Dysphagia Handicap Index (DHI). The discriminant validity was assessed by comparing the KSSQ scores between the participants of both groups. The results indicated that the KSSQ had excellent test-retest reliability, strong internal consistency, and good concurrent and discriminant validity. Therefore, it was inferred that the KSSQ is a valid and reliable tool for assessing the symptoms of dysphagia, especially among Kannada-speaking patients with oropharyngeal dysphagia.

Identifying Psychosocial and Ecological Determinants of Enthusiasm In Youth: Integrative Cross-Sectional Analysis Using Machine Learning.

BACKGROUND: Understanding the factors contributing to mental well-being in youth is a public health priority. Self-reported enthusiasm for the future may be a useful indicator of well-being and has been shown to forecast social and educational success. Typically, cross-domain measures of ecological and health-related factors with relevance to public policy and programming are analyzed either in isolation or in targeted models assessing bivariate interactions. Here, we capitalize on a large provincial data set and machine learning to identify the sociodemographic, experiential, behavioral, and other health-related factors most strongly associated with levels of subjective enthusiasm for the future in a large sample of elementary and secondary school students. OBJECTIVE: The aim of this study was to identify the sociodemographic, experiential, behavioral, and other health-related factors associated with enthusiasm for the future in elementary and secondary school students using machine learning. METHODS: We analyzed data from 13,661 participants in the 2019 Ontario Student Drug Use and Health Survey (OSDUHS) (grades 7-12) with complete data for our primary outcome: self-reported levels of enthusiasm for the future. We used 50 variables as model predictors, including demographics, perception of school experience (i.e., school connectedness and academic performance), physical activity and quantity of sleep, substance use, and physical and mental health indicators. Models were built using a nonlinear decision tree-based machine learning algorithm called extreme gradient boosting to classify students as indicating either high or low levels of enthusiasm. Shapley additive explanations (SHAP) values were used to interpret the generated models, providing a ranking of feature importance and revealing any nonlinear or interactive effects of the input variables. RESULTS: The top 3 contributors to higher self-rated enthusiasm for the future were higher self-rated physical health (SHAP value=0.62), feeling that one is able to discuss problems or feelings with their parents (SHAP value=0.49), and school belonging (SHAP value=0.32). Additionally, subjective social status at school was a top feature and showed nonlinear effects, with benefits to predicted enthusiasm present in the mid-to-high range of values. CONCLUSIONS: Using machine learning, we identified key factors related to self-reported enthusiasm for the future in a large sample of young students: perceived physical health, subjective school social status and connectedness, and quality of relationship with parents. A focus on perceptions of physical health and school connectedness should be considered central to improving the well-being of youth at the population level.

Self-perceived cognitive impairment in the first year after breast cancer and the identification of at-risk patients.

PURPOSE: This study investigated self-reported clinically relevant cognitive impairment of breast cancer patients in routine clinical care and assessed factors associated with new-onset clinically relevant cognitive impairment. METHODS: Cognitive functioning was assessed before start of any treatment (T0) and at 6 (T6) and 12 (T12) months after diagnosis. Cognitive functioning (CF) was measured on a scale of 0-100 with the EORTC QLQ-C30 questionnaire, and the EORTC pre-defined threshold for clinical importance. Multivariable logistic regression analyses was used to identify factors associated with new-onset clinically relevant cognitive impairment at T6 ((CF > 75 at T0 and CF < 75 at T6 and T12) or (CF > 75 at T0 and T6 and <75 at T12)). RESULTS: Pre-treatment, 21% of patients reported clinically relevant cognitive impairment. At T12, percentage was 32%; 20% of patients reported new-onset clinically relevant cognitive impairment at T6 and/or T12. New-onset clinically relevant cognitive impairment was associated with chemo(immuno)therapy and impairment in role and emotional functioning. Younger patients and patients receiving chemo(immuno)therapy were more likely to report new-onset clinically relevant cognitive impairment post treatment. CONCLUSION: One in five breast cancer patients reported clinically relevant cognitive problems before start of treatment. This percentage further increased within the first year, particularly among patients treated with chemo(immuno)therapy. One in five patients reported new-onset clinically relevant cognitive impairment. Ultimately, these patients may benefit from systematic monitoring and potential referral to interventions.

Brain reserve and timing of clinical onset in multiple sclerosis.

BACKGROUND: A latent period of variable length elapses between multiple sclerosis (MS) biological onset and the occurrence of the first clinical episode reflecting a central nervous system (CNS) demyelinating event. Factors affecting the duration of such interval are unknown. OBJECTIVE: To explore whether brain reserve, which moderates the impact of structural damage along MS course, could also affect the timing of MS clinical onset. METHODS: We conducted a time-to-event analysis in 326 relapsing-onset multiple sclerosis patients to ascertain the effect of brain reserve, that is, larger maximal lifetime brain growth (MLBG) estimated as intracranial volume, on the risk of an earlier disease onset. For this purpose, we carried out a Cox proportional hazards regression model stratified by sex and adjusted by site and pre-morbid MS risk factors. All patients reached the event (i.e. the disease onset) with no censored case; the age (years) at disease onset was set as the main time variable. RESULTS: We identified a protective effect of brain reserve on the time to disease onset (HR = 0.11, 95% CI = 0.02-0.83, p = 0.032), unchanged when accounting for MS risk factors. CONCLUSION: Brain reserve might counteract the pathological mechanisms ongoing after biological initiation, thus delaying the disease overt clinical manifestation.

Subjective cognitive and olfactory impairments predict different prospective dementia outcomes.

Self-reported measures emerge as potential indicators for early detection of dementia and mortality. We investigated the predictive value of different self-reported measures, including subjective cognitive decline (SCD), subjective olfactory impairment (SOI), subjective taste impairment (STI), and self-reported poor health (SPH), in order to determine the risk of progressing to Alzheimer's disease (AD) dementia, Parkinson's disease (PD) dementia, or any-other-cause dementia. A total of 6,028 cognitively unimpaired individuals from the 8th wave of the English Longitudinal Study of Ageing (ELSA) were included as the baseline sample and 5,297 individuals from the 9th wave were included as 2-year follow-up sample. Self-rated measures were assessed using questions from the ELSA structured interview. Three logistic regression models were fitted to predict different the dementia outcomes. SCD based on memory complaints (OR = 11.145; P < 0.001), and older age (OR = 1.108, P < 0.001) significantly predicted the progression to AD dementia at follow-up. SOI (OR = 7.440; P < 0.001) and older age (OR = 1.065, P = 0.035) significantly predicted the progression to PD dementia at follow-up. Furthermore, SCD based on memory complaints (OR = 4.448; P < 0.001) jointly with complaints in other (non-memory) mental abilities (OR = 6.662; P < 0.001), and older age (OR = 1.147, P < 0.001) significantly predicted the progression to dementia of any other cause. Different types of complaints are specifically associated with different dementia outcomes. Our study demonstrates that self-reported measures are a useful and accessible tool when screening for individuals at risk of dementia in the general population.

The association between interoception and olfactory affective responses.

Odors are known to affect an individual's emotions and physiological states. Recent research has revealed that olfaction is linked to the mental representation of internal sensations, known as interoception. However, little research has examined how interoception relates to emotional responses to odors. This research aimed to fill this gap in the literature. We conducted two studies with a total of 548 Japanese women (n = 500 and n = 48 in Studies 1 and 2, respectively). Study 1 used an online survey to assess the relationship between self-reported interoceptive traits and the intensity of positive emotions in response to daily odors. Study 2 examined how self-reported interoceptive traits modulated the arousal ratings of odors presented in the laboratory and the concordance between these perceived arousal ratings and odor-evoked physiological responses. Study 1 confirmed that self-reported interoceptive traits were significant predictors of positive emotional intensity of odors. In Study 2, individuals with high interoceptive measure scores showed concordance between their perceived emotional arousal and the physiological responses associated with that emotion, whereas individuals with low scores did not. These findings suggest that how people perceive their internal sensations contributes to shaping their olfactory affective experiences, thereby broadening the scope of interoception research and aromachology. The practical implications of these findings for the development of commercial fragrances are discussed.

Unreliable association between self-reported sense of direction and peripheral vestibular function.

BACKGROUND: Uni- or bilateral peripheralvestibular impairment causes objective spatial orientation deficits, which can be measured using pen-and-paper-tests or sensorimotor tasks (navigation or pointing). For patients' subjective orientation abilities, questionnaires are commonly used (e.g., Santa Barbara sense of direction scale [SBSODS]). However, the relationship between subjective assessment of spatial skills and objective vestibular function has only been scarcely investigated. METHODS: A total of 177 patients (mean age 57.86 ± 17.53 years, 90 females) who presented in our tertiary Center for Vertigo and Balance Disorders underwent neuro-otological examinations, including bithermal water calorics, video head impulse test (vHIT), and testing of the subjective visual vertical (SVV), and filled out the SBSODS (German version). Correlation analyses and linear multiple regression model analyses were performed between vestibular test results and self-assessment scores. Additionally, groupwise vestibular function for patients with low, average, and high self-report scores was analyzed. RESULTS: Forty-two patients fulfilled the diagnostic criteria for bilateral vestibulopathy, 93 for chronic unilateral vestibulopathy (68 unilateral caloric hypofunction and 25 isolated horizontal vestibulo-ocular reflex deficits), and 42 patients had normal vestibular test results. SBSODS scores showed clear sex differences with higher subjective skill levels in males (mean score males: 4.94 ± 0.99, females 4.40 ± 0.94; Student's t-test: t-3.78, p < .001***). No stable correlation between objective vestibular function and subjective sense of spatial orientation was found. A multiple linear regression model could not reliably explain the self-reported variance. The three patient groups with low, average, and high self-assessment-scores showed no significant differences of vestibular function. CONCLUSION: Self-reported assessment of spatial orientation does not robustly correlate with objective peripheral vestibular function. Therefore, other methods of measuring spatial skills in real-world and virtual environments are required to disclose orientation deficits due to vestibular hypofunction.

ICF-based hearing and functioning assessment: validation and research outcomes of utilizing the HEAR-COMMAND tool for patients with mild to moderately severe hearing loss and individuals with normal hearing.

Objective: Current clinical assessments for Hearing Loss (HL) are often limited to controlled laboratory settings in which a narrow spectrum of hearing difficulties can be assessed. A majority of the daily life challenges caused by HL cannot be measured in clinical methodologies. To screen the individuals' needs and limitations, a questionnaire named the HEAR-COMMAND tool was developed and qualitatively validated through an international collaboration, aligning with the World Health Organization's International Classification of Functioning, Disability, and Health Framework (ICF) Core Sets for Hearing Loss. The tool empowers healthcare professionals (HCPs) to integrate the ICF framework into patient assessments and patient-reported outcomes (PRO) in clinical and non-clinical settings. The aim is to provide a general foundation and starting point for future applications in various areas including ENT and hearing acoustics. The outcome can be employed to define and support rehabilitation in an evidence-based manner. This article presents the validation and research outcomes of using the tool for individuals with mild to moderately severe HL in contrast to normal-hearing individuals. Design: Using a cross-sectional multicenter study, the tool was distributed among 215 participants in Germany, the USA, and Egypt, filled in German, English, or Arabic. Three outcome scores and the corresponding disability degree were defined: hearing-related, non-hearing-related, and speech-perception scores. The content and construct validation were conducted, and the tool's internal consistency was assessed. Results: The extracted constructs included "Auditory processing functionality", "Sound quality compatibility", "Listening and communication functionality", "Interpersonal interaction functionality and infrastructure accessibility", "Social determinants and infrastructure compatibility", "Other sensory integration functionality", and "Cognitive functionality". Regarding content validity, it was demonstrated that normal-hearing participants differed significantly from individuals with HL in the hearing-related and speech-perception scores. The reliability assessment showed a high internal consistency (Cronbach's alpha = 0.9). Conclusion: The outcome demonstrated the HEAR-COMMAND tool's high content and construct validity. The tool can effectively represent the patient's perspective of HL and hearing-related functioning and enhance the effectiveness of the treatment plans and rehabilitation. The broad range of targeted concepts provides a unique overview of daily life hearing difficulties and their impact on the patient's functioning and quality of life.

Male football players have better patient-reported outcomes after primary anterior cruciate ligament reconstruction compared with females.

BACKGROUND: Sex differences in patient-reported outcomes (PROs) are not well investigated after anterior cruciate ligament (ACL) reconstruction in football players. The aim was to study sex differences in player-related factors, ACL injury characteristics and PROs after primary ACL reconstruction in football players. METHODS: In this cross-sectional cohort study a survey was sent to 390 male and 403 female football players who were injured when playing football and had undergone a primary ACL reconstruction in the previous 1-3 years. Player-related factors, ACL injury characteristics, and PROs covering knee function, satisfaction with activity level and knee function, and readiness to return to sport were compared between male and females. The questionnaires International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC-SKF), Knee injury and Osteoarthritis Outcome Score (KOOS), ACL-Quality of Life (ACL-QoL) and ACL-Return to Sport after Injury (ACL-RSI) were used. RESULTS: Ninety males (23%) and 283 (70%) females answered the survey, 65 males and 198 females fulfilled the inclusion criteria. Males had returned to football to a higher degree (77% vs 59%, p = 0.008) at any time after ACL reconstruction, but at the time of the survey, an equal number of males and females played football (55% vs 47%, p = 0.239) and had similar activity level according to the Tegner Activity Score (median, 9; interquartile range [IQR], 7, vs median, 8; IQR, 7; p = 0.740). Males were more satisfied with their knee function and activity level and rated higher scores in the IKDC-SKF (mean ± standard deviation, 83 ± 16 vs 76 ± 16, p = 0.006), KOOS Sport/Recreation (79 ± 19 vs 72 ± 22, p = 0.034), KOOS Quality of Life (73 ± 22 vs 64 ± 20, p = 0.008), ACL-QoL (7.6 ± 2 vs 6.8 ± 1.8, p = 0.008), and ACL-RSI (6.7 ± 2.1 vs 5.5 ± 2.3, p < 0.001) than females (all with small - medium effect sizes). CONCLUSIONS: Male football players reported more favourable results than females in patient-reported knee function, satisfaction with activity level and knee function, knee-related quality of life and psychological readiness to return to sport 1-3 years after ACL reconstruction. The results contribute to a better understanding of the eventual effect of patient sex on outcomes after ACL reconstruction in football players. However, the clinical importance of these differences is unclear.

Association between predicted level of water turnover deficit and all-cause and cause-specific mortalities among Japanese adults: The Japan Collaborative Cohort Study.

BACKGROUND: Although water is essential for maintaining health and life, the association between water turnover as an indicator of daily water requirement and water deficit and mortality is unclear. OBJECTIVE: We aimed to investigate this association in Japanese adults. METHODS: A total of 63,488 (36,739 females and 26,749 males) Japanese aged 40-79 years in the Japan Collaborative Cohort Study in 1988-1990 were followed up their mortality through 2009. Water turnover was calculated considering lifestyle and environmental factors using an equation previously developed by the International Doubly Labeled Water Database Group. Participants were classified into sex-specific quintiles based on their water turnover. Water deficit levels were calculated from water turnover and dietary water consumption, which were estimated using a validated questionnaire. RESULTS: The average daily water turnovers were 2,950 mL and 3,466 mL in females and males, respectively. During 19.4 years of median follow-up (1,039,914 person-years), 12,551 deaths were recorded. After adjusting for lifestyle and medical history, the bottom quintile was associated with higher hazard ratios (HRs) of mortality from all causes (females: HR, 1.26; 95% confidence interval, 1.12, 1.41; males: HR, 1.18; 95% CI, 1.07, 1.29) and cardiovascular disease (CVD). In spline analyses, the water turnover range with the lowest HR for all-cause mortality was 3,000-3,300 mL/day in females and the water turnover at which the HR for all-cause mortality plateaued was approximately 3,500-3,700 mL/day in males. Water deficiency levels were associated with all-cause and CVD mortality in both sexes. CONCLUSION: This study showed an L-shaped association between water turnover and deficit and all-cause and CVD mortalities (especially coronary heart disease and ischemic stroke) in adults. These findings may be useful for setting the target values of water requirement, and differences between dietary requirements and actual intake may bridge the knowledge gap in water-mortality associations.

Adaptation of a standardized self-reported cost questionnaire specific for the severe burn injury population (BI-CoPaQ).

Severe burn injuries (SBIs) are known to pose a significant burden on patients, caregivers, and the healthcare system. Yet, scarce data on the short and long-term clinical and economic impacts of these injuries limit the development of evidence-informed strategies and policies to better care for these patients. To fill in this gap, we adapted a previously validated self-reported out-of-pocket cost measurement questionnaire, the Cost for Patients Questionnaire (CoPaQ), to the severe burn injury survivor context. We conducted one-on-one cognitive semi-structured interviews with burn injury survivors, their caregivers, and healthcare providers to identify elements of the CoPaQ's structure and content that needed to be revised to adapt to the specific health care trajectory, service utilization, needs and expenses incurred by adult severe burn injury survivors and their caregivers. Summative content analysis was used to identify items needing to be modified, deleted, or added. Based on this information, a preliminary version of a Burn Injury Cost for Patients Questionnaire (BI-CoPaQ) was developed and subsequently pre-tested on a small sample of SBIs survivors. Further validation of this tool will be required before BI-CoPaQ can be used as the standard for the estimation of the financial burden of SBIs in this population.
