Polish language adaptation and validation of the Fonseca Anamnestic Index for individuals with temporomandibular disorders.

Given the notable prevalence of temporomandibular disorders (TMD) in the Polish population, there is a clear need for the use of simple, reliable questionnaires as screening tools to facilitate the referral of patients to TMD specialists. The aim of the study was to translate and adapt the Fonseca Anamnestic Index (FAI) into Polish and assess its reliability and validity in identifying TMD symptoms. The Polish adaptation of the FAI (FAI-PL) was developed in accordance with the international guidelines, including the translation and evaluation of the psychometric properties of the questionnaire. Every patient received a standardized assessment, which involved history taking and clinical examination, including the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and the FAI questionnaire. The psychometric analyses included an evaluation of the questionnaire's reliability and validity, as well as an exploratory factor analysis (EFA). Of the 122 individuals enrolled in the study, 63.9% were female. The mean age of the participants was 28.1 years (standard deviation (SD): 6.3). According to the RDC/TMD standards, 40.9% of patients had no TMD, while the FAI assessment indicated that 27% of patients had no TMD. The Cronbach's alpha coefficient for the FAI-PL was 0.75. The exploratory factor analysis revealed 3 factors, accounting for 55.2% of the total variation. The diagnostic sensitivity of the FAI-PL was 98.6%, while the diagnostic specificity reached a level of 65.3%. The Polish version of the FAI is a reliable and valid tool for the screening of TMD symptoms in the Polish-speaking population.

Impact of advanced trauma life support training on 30-day mortality in severely injured patients at a Kenyan tertiary center: a retrospective matched case-control study

IntroductionTrauma is a leading cause of mortality worldwide, particularly in low and middle-income countries (LMICs) like Kenya. This study evaluates the impact of Advanced Trauma Life Support (ATLS) training on 30-day mortality outcomes in severely injured patients at a tertiary care center in Kenya.MethodsA retrospective matched case-control study was conducted at Aga Khan University Hospital, Nairobi. The study included adult patients (≥ 18 years) with polytrauma (Injury Severity Score [ISS] > 15) from 2011 to 2022. Propensity score matching was used to pair 81 post-ATLS cases with 81 pre-ATLS controls based on age and ISS. Data analysis was performed using R Statistical language (version 4.3.0).ResultsThe 30-day mortality rate decreased significantly from 17% (95% CI: 9.4–27.4%) pre-ATLS to 6% (95% CI: 2.0-13.5%) post-ATLS (p = 0.028). No significant differences were found in baseline characteristics between the two groups. Road traffic accidents were the primary cause of trauma in both groups (72% pre-ATLS vs. 78% post-ATLS).ConclusionATLS training significantly reduced 30-day mortality in severely injured patients, demonstrating its effectiveness even in resource-limited settings. Further prospective randomized studies are recommended to confirm these findings and evaluate long-term outcomes.

Loanwords in Modern German: Exploring Phonetic and Grammatical Adaptations

This study explores the phonetic and grammatical adaptation of loanwords in modern German, focusing primarily on borrowings from English and French. The research examines how foreign sounds are adjusted to fit German phonology, with particular attention to vowel and consonant shifts, as well as stress patterns. Additionally, the study investigates how loanwords are integrated grammatically, analyzing gender assignment, pluralization, and inflection. Findings reveal that while loanwords generally conform to native German grammatical rules, exceptions exist, particularly in gender assignment and pluralization. The study also highlights the influence of globalization, especially through English loanwords in business and technology, which often retain their original pronunciation and pluralization. These results contribute to the understanding of language contact, borrowing, and adaptation in a globalized linguistic environment.

Noise sensitivity: from systematic review to improving its measurement

Noise sensitivity is known to be the most influential non-acoustic factor affecting noise annoyance. While there is general consensus within the international research community as to how noise annoyance should be measured, it is not true for noise sensitivity. Either single-item rating scales are used or full-fledged questionnaires. Few of these instruments have been validated across different languages, and some of them have never been psychometrically evaluated. Even though noise sensitivity has been studied for many decades, there is no systematic review of what noise sensitivity is. The present research program started out by conducting a systematic review of the instruments available to measure noise sensitivity. Next, an online survey will be carried out to evaluate and compare existing noise-sensitivity questionnaires on a large sample while considering versions in different languages. Finally, on the basis of both the systematic review and the questionnaire evaluation, a resulting measure of noise sensitivity will be assessed in the laboratory by relating it to both noise annoyance and physiological measurements. The relevance of the proposed work is thus to designate a reliable, yet economic method to measure noise sensitivity in future surveys.

The relationship between social odour awareness and emotional contagion susceptibility in females.

Previous research has shown a strong link between our sense of smell and emotion. More recently, the importance we attach to olfaction has been found to relate to our susceptibility to 'catch' the emotions of others. We explore this further by examining the relation between a newly developed measure of olfaction (social odour scale, SOS), which measures awareness of social odours, and emotional contagion susceptibility in female participants. The study therefore aimed to test the strength of this relationship and also help validate the English language version of the SOS. Female (n = 148) participants completed an online study that measured odour awareness [SOS; important of odour questionnaire, IOQ] and emotional contagion (EC). We found that the English version of the SOS yielded high reliability and supported the previous factor structure of the scale; additionally, we demonstrated a strong association between the SOS and IOQ which provides criterion validity for its usage. The study also revealed that whilst both the SOS and IOQ were positively associated with EC, the SOS was the more accurate predictor. These findings provide further validation for the use of the SOS and suggest that our subjective awareness of olfaction, especially concerning 'social odours' is an accurate predictor of emotional contagion.

THE PROBLEMS OF TRANSLATING BOARD GAMES AS EXEMPLIFIED BY THE TRANSLATION OF SELECTED PROPER NAMES IN THE GAME EVERDELL INTO POLISH AND RUSSIAN The main aim of this paper is to analyse the Polish and Russian translations of selected proper names from the board game Everdell and its expansions, issued by Starling Games in 2018-2020. The author focuses on the theory of translating (transcreating) board game as a multimodal text and potential translation issues, as well as on the translator’s competences. The analytic part of this work consists of seven selected proper names translated into Polish by Monika Żabicka and into Russian by Daniil Yakovenko, Evgeniia Nekrasova and Stanislav Zagorodnyi: Everdell, Ever Tree, Corrin Evertail, Fynn Nobletail, Poe, Prophet Foresight and Pristine Chapel. The author shows their etymological, historical, and cultural background presented in the source language and then discusses their Polish and Russian equivalents and strategies chosen by the translators. As a result, we can see that the proper names in the Polish version are mostly adapted and relate to the Polish culture and history, whereas in Russian language version most of the proper names are not translated, just transcribed.

Aspects of effective communication (european experience): digital, informational, and sociolinguistic dimensions

Introduction: The modern era of digital technologies and globalization has brought about significant transformations in communication methods. This article explores how digital, informational, and sociolinguistic dimensions influence the processes of effective communication, focusing particularly on European experiences.Objective: The objective of this study is to analyze the impact of digital transformation, information transparency, linguistic diversity, and cultural adaptation on effective communication in modern European society. The research aims to uncover both the benefits and challenges posed by these factors in the context of communication processes.Methods: This research employed a theoretical approach, synthesizing a wide range of literature and conducting psychological and sociolinguistic analyses. Comparative methods were used to assess different strategies of communication in European contexts, while particular attention was paid to understanding how digitalization and sociolinguistic factors interact.Results: The findings suggest that digitalization enhances accessibility and the speed of communication but introduces challenges, such as the digital divide and data protection issues. Information transparency and accessibility have been identified as crucial in building trust and ensuring the effective exchange of information. Moreover, sociolinguistic factors, especially cultural and language adaptation, have proven essential for effective intercultural communication in Europe.Conclusions: The study concludes that successful communication strategies must incorporate digital, informational, and sociolinguistic aspects, particularly in multilingual and culturally diverse contexts. Awareness and adaptation to cultural norms and linguistic nuances are vital for creating more effective communication practices in both international and local interactions. Practical recommendations include focusing on cultural sensitivity and data transparency to further enhance communication processes

Prenatal Surgery for Open Fetal Spina Bifida in Patients with Obesity: A Review of Current Evidence and Future Directions.

Background: Obesity rates have significantly increased globally, affecting up to 40% of women of childbearing age in the United States. While prenatal repair of open fetal spina bifida has shown improved outcomes, most fetal surgery centers exclude patients with a body mass index (BMI) ≥ 35 kg/m2 based on criteria from the Management of Myelomeningocele Study (MOMS) trial. This exclusion raises concerns about healthcare equity and highlights a significant knowledge gap regarding the safety and efficacy of fetal spina bifida repair in patients with obesity. Objective: To review the current state of knowledge regarding open fetal surgery for fetal spina bifida in patients with obesity, focusing on safety, efficacy, and clinical considerations. Methods: A comprehensive literature search was conducted using the PubMed and EMBASE databases, covering articles from the inception of the databases to April 2024. Studies discussing fetal surgery for neural tube defects and documenting BMI measurements and their impact on surgical outcomes, published in peer-reviewed journals, and available in English were included. Quantitative data were extracted into an Excel sheet, and data synthesis was conducted using the R programming language (version 4.3.3). Results: Three retrospective studies examining outcomes of prenatal open spina bifida repair in a total of 43 patients with a BMI ≥ 35 kg/m2 were identified. These studies did not report significant adverse maternal or fetal outcomes compared to patients with lower BMIs. Our pooled analysis revealed a perinatal mortality rate of 6.1% (95% CI: 1.76-18.92%), with 28.0% (95% CI: 14.0-48.2%) experiencing the premature rupture of membranes and 82.0% (95% CI: 29.2-98.0%) delivering preterm (<37 weeks). Membrane separation was reported in 10.3% of cases (95% CI: 3.3-27.7%), the mean gestational age at birth was 34.3 weeks (95% CI: 32.3-36.3), and the average birth weight was 2651.5 g (95% CI: 2473.7-2829.4). Additionally, 40.1% (95% CI: 23.1-60.0%) required a ventriculoperitoneal shunt. Conclusion: While current evidence suggests that fetal spina bifida repair may be feasible in patients with obesity, significant limitations in the existing body of research were identified. These include small sample sizes, retrospective designs, and a lack of long-term follow-up data. There is an urgent need for large-scale, prospective, multicenter studies to definitively establish the safety and efficacy of fetal spina bifida repair in patients with obesity. Such research is crucial for developing evidence-based guidelines, improving clinical outcomes, and addressing healthcare disparities in this growing patient population with obesity.

Validation of the Jamaican version of the Oral Health Impact Profile (OHIP-14) in adults: JAM-OHIP study

Background: The Oral Health Impact Profile (OHIP-14) is a widely used tool for measuring the effects of oral health-related quality of life (OHRQoL). However, the validity of the OHIP-14 in the Jamaican context, referred to as the Jamaican Oral Health Impact Profile (JAM-OHIP), has yet to be established. Purpose: To determine the validity of the Jamaican language version of the OHIP in evaluating the OHRQoL of Jamaican adults. Methods: The original English version of the Oral Health Impact Profile (OHIP-14) was translated into the Jamaican language using forward and backward translation. The JAM-OHIP was used to evaluate the OHRQoL of 236 individuals at the University of the West Indies Dental Polyclinic. The overall fit was checked using a chi-square test (p &gt; 0.05), comparative fit index (CFI), Tucker–Lewis index (TLI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). Results: More DMFT (p &lt; 0.01) was associated with high JAM-OHIP scores, and the most impacted domain was physical pain. Cronbach’s alpha and the standardized item alpha for the JAM-OHIP were 0.82. The overall fitting results for the CFA were χ²(68) = 80.558, p = 0.142, and χ²/g.l. = 1.185. The CFI and TLI were 0.996 and 0.994, respectively. The SRMR was 0.072 and the RMSEA was 0.028 (CI95% = [0.000; 0.050]) p = 0.953. Conclusions: The JAM-OHIP instrument was shown to be reliable and valid for the assessment of OHRQoL in the Jamaican adult population.

B - 102 Neurocognitive Functioning of Patients Diagnosed with Sickle Cell Disease in Low-to-Middle Income Countries

Abstract Objective Sickle Cell Disease (SCD) is a monogenic blood disorder affecting the production of hemoglobin, a protein that carries oxygen to all vital organs in the body. As a result, insufficient oxygen delivery and cerebrovascular complications often occur which can affect neurocognitive performance. In low-to-middle-income countries (LMIC) where health care and treatment of the disease are harder to access, there is minimal neurocognitive surveillance. Our research aim was to evaluate the neurocognitive impact of SCD in children living in LMIC and establish which neurocognitive assessment measures are commonly used in SCD samples worldwide. Data Selection To analyze this, a librarian created search terms in studies from Embase, PubMed, Web of Science, Global Health CABI, ERIC, CINAHL, and PsycINFO. Studies that focused on participants with SCD of any genotype with a measure for cognitive/academic outcomes were included while commentaries and editorials were excluded. Two research assistants screened 1831 abstracts in Covidence, 52 abstracts were chosen for full-text review, and 18 articles were ultimately included for data extraction. Data Synthesis A systematic review was used to analyze these studies. Most of the studies were conducted in African and Middle Eastern countries and Brazil. Common measures included the Wechsler Intelligence Scale for Children or Adults. Information regarding cultural or language adaptations of neurocognitive measures was rarely reported. Several of the studies demonstrated that individuals with SCD have lower neurocognitive functioning compared to a non-SCD control group. Conclusion Further research is needed regarding the validity of neurocognitive measures used in LMIC among patients diagnosed with SCD.

Expression Profile and Prognostic Values of IRX Family Members in Lung Adenocarcinoma.

The potential role of the iroquois homeobox (IRX) genes in tumorigenesis is a subject of interest, yet their specific involvement in lung adenocarcinoma (LUAD) has not been extensively examined. This research endeavored to explore the impact of the IRX genes on the onset and progression of LUAD. Utilizing data from The Cancer Genome Atlas (TCGA), samples of LUAD were selected for analysis. The influence of the IRX genes was scrutinized through various tools, including Kaplan-Meier Plotter, cBioPortal, and the R programming language (version 3.6.3), with gene expression levels being confirmed in cellular models via quantitative real-time polymerase chain reaction (qRT-PCR). It was observed that the levels of IRX1/2/3/6 were notably diminished in LUAD tissues when juxtaposed with healthy lung tissue. Conversely, the expression of IRX4 was found to be elevated in LUAD. Correlations were identified between IRX gene expression and several clinical parameters such as T stage, smoking history quantified in pack-years, lymph node involvement, patient gender, initial treatment responses, and smoking status. The diminished expression of IRX2/5 emerged as a significant indicator of an unfavorable prognosis in LUAD. The study also highlighted the potential of various IRX genes as diagnostic indicators for LUAD. These genes were implicated in the facilitation of LUAD's growth and spread through a range of biological pathways, encompassing the Ras signaling and more. Additionally, a pronounced link was discovered between the infiltration of immune cells and the expression patterns of the IRX genes. IRX genes were abnormally expressed in LUAD cell lines. IRX gene family could serve not only as indicators of LUAD prognosis but also as therapeutic targets for LUAD.

Cooling Uncovered Foods at a Depth of ∼5.1 cm (2 in.) or Less Poses Little Risk of Pathogen Growth

The U.S. Food and Drug Administration has guidelines for cooling cooked foods in retail operations. Data on foodborne illness risk factors in restaurants indicate that cooling is often out of compliance with these guidelines. We sought to identify factors under the control of the operator that had a significant effect on the cooling rates of cooked foods. Minneapolis Minnesota Health Inspectors were trained in standardized operating procedures for cooling data collection. Data loggers set to appropriate time intervals and calibrated to ±0.5 °C (∼1°F) were used in data collection. Analysis was performed using the R statistical computing language version 4.2.2. Preexisting pathogen models were used to predict Log CFU increases of Clostridium perfringens or Bacillus cereus. Data from 224 recipes were recorded by inspectors between October 2018 and October 2019. Food depth had a highly significant effect (p = 8.90E−08) on cooling rate. The use of an ice bath or ice wand was also significant (p < 0.005). There was a significant correlation between container material (metal or plastic) and food depth because foods with a greater depth are often being cooled in plastic containers. Foods at a depth greater than 5.1 cm (2 in.) that cooled faster than 0.23 log(°C)/h were often wholly or partially cooled in blast chillers or freezers, cooled using an ice bath or ice wand (or both), or were composed of protein pieces (e.g., chicken wings) that facilitated more rapid cooling due to air gaps in the food. Foods in shallow containers at a food depth of less than or equal to ∼5.1 cm (2 in.) that cooled more slowly than 0.23 log(°C)/h were being cooled at temperatures greater than 5 °C (41°F) or were partially or wholly covered. These foods also showed little evidence of pathogen growth from predictive models. Our analysis shows that cooling foods in shallow containers at a food depth of less than or equal to ∼5.1 cm (2 in.) poses little risk of significant pathogen growth.

The multilingual digits-in-noise (DIN) test: development and evaluation

Objective To develop a methodologically uniform digits-in-noise (DIN) test in 17 different languages. Design The DIN test was developed for Android devices as an extension to the open-access Hearing Test™ app, available on the Google Play store. It utilised professionally recorded female speech, speech-shaped noise, a digit scoring method and a variable step size. The test was adaptively optimised and evaluated as the results of tests taken online by users of the app became available. Study sample Optimisation using 35,534 ears, evaluation using 6012 ears. Results Optimisation improved the slopes of the psychometric functions for all languages by an average of 6.8%/dB. Evaluation included calculation of normative speech reception thresholds (SRTs) and estimation of test-retest standard deviations. Normative values for SRTs ranged from −14.2 dB SNR (95% CI −14.3 to −14.0) for Chinese to −11.2 dB SNR (95% CI −11.3 to −11.1) for Japanese, with reliability estimates ranging from 0.48 dB (95% CI 0.36–0.64) for Portuguese to 0.91 dB (95% CI 0.73–1.21) for Romanian. Conclusions The optimisation of each language version was confirmed by the improvement in the slopes of the psychometric functions. The normative values obtained from the test evaluation were in agreement with literature data. Trial Registration Science Support Centre of Wroclaw Medical University BW-59/2020

Improving outcome measures in late onset Pompe disease: Modified Rasch-Built Pompe-Specific Activity scale.

The Rasch-Built Pompe-Specific Activity (R-PAct) scale is a patient-reported outcome measure specifically designed to quantify the effects of Pompe disease on daily life activities, developed for use in Dutch- and English-speaking countries. This study aimed to validate the R-PAct for use in other countries. Four other language versions (German, French, Italian, and Spanish) of the R-PAct were created and distributed among Pompe patients (≥16 years old) in Germany, France, Spain, Italy, and Switzerland and pooled with data of newly diagnosed patients from Australia, Belgium, Canada, the Netherlands, New Zealand, the USA, and the UK and the original validation cohort (n = 186). The psychometric properties of the scale were assessed by exploratory factor analysis and Rasch analysis. Data for 520 patients were eligible for analysis. Exploratory factor analysis suggested that the items separated into two domains: Activities of Daily Living and Mobility. Both domains independently displayed adequate Rasch model measurement properties, following the removal of one item ("Are you able to practice a sport?") from the Mobility domain, and can be added together to form a "higher order" factor as well. Differential item functioning (DIF)-by-language assessment indicated DIF for several items; however, the impact of accounting for DIF was negligible. We recalibrated the nomogram (raw score interval-level transformation) for the updated 17-item R-PAct scale. The minimal detectable change value was 13.85 for the overall R-PAct. After removing one item, the modified-R-PAct scale is a valid disease-specific patient-reported outcome measure for patients with Pompe disease across multiple countries.

The linguistic and construct validity of the Malay version of the Coping Self-Efficacy Scale (CSES-My): Evidence from a sample of Malaysian parents of children with leukemia or lymphoma.

Parents of children with hematological cancers such as leukemia and lymphoma need to cope with stress related to their child's diagnosis. The Coping Self-Efficacy Scale is a widely used and validated tool to measure an individual's confidence in dealing with stressful situations. Appropriate translation and validation are needed to produce a localized language version suitable for Malaysian contexts. The study aimed to examine the linguistic and construct validity of the Malay version of the Coping Self-Efficacy Scale (CSES-My) among parents of children with hematological cancer. The CSES-My was created through a sequential series of steps, starting with the translation of the original English version, followed by cultural adaptation, and then cognitive interviewing. The 26-item CSES-My was self-administered in a sample of parents of children with leukemia and lymphoma from October 2021 until February 2022. They were recruited via online or face-to-face methods. Exploratory factor analysis was performed to examine the construct validity of the CSES-My. A total of 165 complete responses were analyzed. The scale has two factors, including Personal Coping and Social Coping, accounting for 58.3% of the variance. Personal Coping (19 items, Cronbach's alpha = 0.958) represented the respondents' self-efficacy for independently executing coping strategies, whether through solving problems or changing the way they think about the situation. Social Coping (6 items, Cronbach's alpha = 0.867) represented their confidence in executing coping strategies, which involved using social resources such as seeking external support, distraction, and avoiding loneliness. The CSES-My had reliable and valid psychometric properties, providing evidence for its utility in evaluating coping self-efficacy among parents of children with leukemia or lymphoma in Malaysia. The CSES-My is a valuable tool for nurses and other healthcare professionals investigating coping self-efficacy in Malay-speaking populations, and it may also aid in the development of future coping interventions.

Multifractal Hopscotch in Hopscotch by Julio Cortázar.

Punctuation is the main factor introducing correlations in natural language written texts and it crucially impacts their overall effectiveness, expressiveness, and readability. Punctuation marks at the end of sentences are of particular importance as their distribution can determine various complexity features of written natural language. Here, the sentence length variability (SLV) time series representing Hopscotch by Julio Cortázar are subjected to quantitative analysis with an attempt to identify their distribution type, long-memory effects, and potential multiscale patterns. The analyzed novel is an important and innovative piece of literature whose essential property is freedom of movement between its building blocks given to a reader by the author. The statistical consequences of this freedom are closely investigated in both the original, Spanish version of the novel, and its translations into English and Polish. Clear evidence of rich multifractality in the SLV dynamics, with a left-sided asymmetry, however, is observed in all three language versions as well as in the versions with differently ordered chapters.

Factors that play a role in international PhD candidates’ social experiences with inclusion and integration in an international learning environment: A narrative inquiry in a Dutch research university

International universities often promote inclusive learning environments to aid their sojourners’ social integration and improve their well-being. However, little is known about how social experiences with inclusion and integration (SEII) unfold for international PhD candidates in Dutch research universities (DRUs). This study uses the narratives of twenty IPCs to understand the factors that play a role in their SEII in a DRU. Findings suggest that nine factors may define SEII among the participants. Two factors—prior experiences in an ILE and identity in PhD role—played a role in participants’ early SEII, while seven factors played a role in participants’ early and later SEII. These included IPCs’ social participation level, intercultural interaction dynamics, shared language adaptation, cultural events, university’s international campus climate, social support, and perceived prejudice and stereotypes. IPCs and their international universities should align expectations to promote an inclusive social climate to foster social integration of IPCs.

German translation, cultural adaptation for Austria and validation of the Neurological Sleep Index - Multiple Sclerosis (NSI-MS).

To translate, culturally adapt, and validate the Neurological Sleep Index - Multiple Sclerosis (NSI-MS) for use in Austrian German-speaking populations with multiple sclerosis (pwMS). Following established guidelines, the NSI-MS diurnal sleepiness (DS), non-restorative nocturnal sleep (NRNS), and fragmented nocturnal sleep (FNS) scales underwent forward-backward translation, with content and face validity, and cultural adaptation to Austria established. Construct validity was evaluated using Rasch analysis. Known-groups validity was examined, and comparisons were made with scales measuring MS fatigue, daytime sleepiness, sleep quality, anxiety, and depression. Reliability was assessed through Cronbach's alpha, Person Separation Index, Lin's concordance correlation coefficient, measurement error, and floor and ceiling effects. Data were merged with a historic English dataset for comparison between English/German language versions. The translation and cultural adaptation of the NSI-MS-G were successful. Pretesting involved 30 pwMS, while the validation included 400 pwMS with mild-to-severe disability. The DS, NRNS, and FNS scales exhibited good fit parameters, were unidimensional, and invariant. NSI-MS-G scales demonstrated excellent convergent and known-groups validity, internal consistency, person separation reliability, test-retest reliability, adequate measurement error, and low floor and ceiling effects. Pooling English and German datasets revealed that person estimates for the NRNS and FNS scales are equivalent across versions, unlike the DS scale. The NSI-MS-G demonstrates validity, reliability, and responsiveness in assessing DS, NRNS, and FNS in pwMS, generating interval-level data, and shows equivalence between its English and German versions.
