Comparative volatiles profiling of two marjoram products via GC-MS analysis in relation to the antioxidant and antibacterial effects.

Marjoram (Origanum majorana L.), also known as "sweet marjoram" or "sweet oregano" is a Mediterranean herbaceous perennial herb cultivated in Egypt and widely consumed as an herbal supplement for treatment of several ailments. The main goal of this study was to assess volatiles' variation in marjoram samples collected from two different widely consumed commercial products using two different extraction techniques viz. head space solid phase microextraction (HS-SPME) and petroleum ether using gas chromatography mass spectrometry (GC-MS) analysis and multivariate data analysis. A total of 20 major aroma compounds were identified in samples extracted with HS-SPME found enriched in monoterpene hydrocarbons and oxygenated compounds. The major volatiles included β-phellandrene (20.1 and 14.2%), γ-terpinene (13.4 and 11.7%), 2-bornene (12.3 and 11.5%), p-cymene (9.8 and 4.6%) terpenen-4-ol (16.4 and 7.5%), sabinene hydrate (16.02 and 8.8%) and terpineol (4.2 and 3.2%) in MR and MI, respectively. Compared with HS-SPME, 51 aroma compounds were identified in marjoram samples extracted with petroleum ether, found more enriched in aliphatic hydrocarbons (42.8 and 73.8%) in MR and MI, respectively. While a higher identification score was observed in the case of solvent extraction, SPME appeared to be more selective in the recovery of oxygenated terpenes to account more for marjoram aroma. Multivariate data analysis using principal component analysis (PCA) revealed distinct discrimination between volatile composition of both marjoram samples. The total phenolic and flavonoid contents in marjoram samples were at (111.9, 109.1µg GA/mg) and (18.3, 19.5µg rutin eq/mg) in MR and MI, respectively. Stronger antioxidant effects were observed in MR and MI samples with IC50 at 45.5 and 56.8µg/mL respectively compared to IC50 6.57µg/mL for Trolox as assayed using DPPH assay. Moderate anti-bacterial effect was observed in MR and MI samples and expressed as a zone of inhibition mostly against Bacillus subtilis (16.03 and 15.9mm), B. cereus (12.9 and 13.7mm), Enterococcus faecalis (14.03 and 13.97mm), and Enterobacter cloacae (11.6 and 11.6mm) respectively.

Speech Perception Outcomes with the Anatomy-Based Fitting Map Among Experienced, Adult Cochlear Implant Users: A Longitudinal Study.

Anatomy-based fitting (ABF), a relatively new technique for cochlear implant programming, attempts to lessen the impact of the electrode insertion location-related frequency-to-place mismatch (FPM). This study aimed to compare vowels and consonant perception in quiet and in noise among experienced adult cochlear implant (CI) users using the ABF and the regular, conventional-based fitting (CBF) map (pre-ABF) over six months. Nine ears from eight experienced adult CI users were included in the experimental and longitudinal research. Using surgical planning software called Otoplan, post-operative computed CT scans were used to determine the locations of intracochlear electrodes and their angle of insertion. The anatomy-based frequency bands were produced by Maestro 9.0 CI fitting software using the Otoplan data. Nonsense syllables with consonant-vowel-consonant (CVC) recognition scores in quiet and noise (+5dB SNR) were compared at baseline, three, and six months after ABF. The vowels involved were /a, i, u/, while the consonants were voiced /b, d, g/ and voiceless /p, t, k/ plosives. Speech pieces were presented at 30 dB SL in a sound-treated room through a loudspeaker positioned at 0° azimuth. On average, the ABF maps shifted center frequency ranging from 0.46 semitones (0.04 octave) at (E12) to 23.94 semitones (1.99 octave) at (E1) as compared to the CBF maps. The mean vowel and consonant identification scores in quiet and in noise were significantly higher in ABF than in CBF (p<0.05) with a large effect size and the trend of improvement was seen with time. Voiced consonants had better scores than the voiceless consonants. The results demonstrated improved perception of vowels and consonants, particularly for sounds containing voicing cues after using the ABF maps. The results also suggested that ABF could be more effective for voice detection in noise. Overall, the findings indicate that correcting place mismatch with an ABF map may improve speech perception, at least among experienced adult cochlear implant users.

Analysis of lactic acid bacteria species in Miang, a post-fermented tea in Thailand, and their potential use as probiotics.

Miang is one of the post-fermented teas made in Northern Thailand. Although lactic acid bacteria are involved in fermentation of Miang, details are still not clear. This study investigated the diversity of Lactobacillaceae bacteria, related to fermentation of Miang. Probiotic potential of isolated Lactobacillaceae bacteria was examined. Lactobacillaceae bacteria were isolated from 52 Miang samples collected from three provinces in northern Thailand and identified by MALDI-TOF MS. Hemolytic activity, antibiotic susceptibility, antimicrobial activity and tolerance to gastrointestinal juice were examined for probiotic potential of isolates. A total of 1,181 Lactobacillaceae bacteria strains were isolated from Miang. The most abundant isolates were Lactiplantibacillus pentosus. Besides Lactiplantibacillus plantarum, Levilactobacillus brevis, Paucilactobacillus suebicus, Lacticaseibacillus pantheris, and Secundilactobacillus collinoides were also found with frequency. Of these isolates, 450 with a high score for MALDI-TOF identification were then screened for probiotic ability. Most isolates were resistant to aminoglycosides and clindamycin. Then, 35 isolates were tested for their antimicrobial activity against pathogens using the well diffusion method, and 31 isolates exhibited inhibition zones against Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enterica serovar Typhimurium, S. enterica serovar Enteritidis, Listeria monocytogenes, Propionibacterium acnes, and Streptococcus mutans. All 31 isolates were non-hemolytic and readily tolerated simulated gastric juice at pH 3 and simulated intestinal juice at pH 8. Miang contains lactic acid bacteria that could potentially be used as probiotics.

Language Experience Influences Sociolinguistic Development: The Role of Speaker Race and Language Attitudes on Bilingual and Monolingual Adults' Accent Processing.

Speaker race and the listener's language experience (i.e., monolinguals vs. bilinguals) have both been shown to influence accent intelligibility independently. Speaker race specifically is thought to be informed by learned experiences (exemplar model) or individual biases and attitudes (bias-based model). The current study investigates speaker race and the listener's language experience simultaneously as well as listeners' attitudes toward non-native speakers and their ability to identify the accent. Overall, 140 White English monolinguals and 140 English/Norwegian bilinguals transcribed 60 Mandarin-accented English sentences presented in noise in the context of a White or East Asian face. Following sentence transcription, participants were asked to rate the strength of the accent heard and completed a short questionnaire that assessed their accent identification ability and their language usage, proficiency, familiarity, and attitudes. Results show that a listeners' ability to identify an accent and their attitudes toward non-native speakers had a significant impact on accent intelligibility and accentedness ratings. Speaker race by itself did not play a role in accent intelligibility and accentedness ratings; however, we found evidence that speaker race interacted with participants' accent identification scores and attitudes toward non-native speakers, and these interactions differed as a function of language experience. Our results suggest that bilinguals' sociolinguistic processing may be more in line with a bias-based model than monolinguals.

Orthonasal and retronasal olfactory function in patients with chronic rhinosinusitis without nasal polyps undergoing endoscopic sinonasal surgery.

Olfactory dysfunction (OD) is a key symptom of chronic rhinosinusitis (CRS). Although extensively studied in CRS with nasal polyps (CRSwNP), OD in CRS without nasal polyps (CRSsNP) remains under-researched. This study aims to assess the prevalence of OD and its evolution in surgically naïve patients with CRSsNP undergoing endoscopic sinus surgery (ESS). This prospective study included 97 participants with CRSsNP (mean age, 46.5 years; 70.1% men) and 97 healthy controls (mean age, 46.5 years; 70.1% men). Participants underwent psychophysical evaluations of orthonasal (using the Sniffin' Sticks test) and retronasal olfaction (using powdered aromas) at enrolment and 6 months post-ESS. Out of 97 patients, 81 (83.5%) completed all assessments. At enrolment, 23 (28.4%) CRSsNP patients had OD based on composite threshold, discrimination, identification scores, compared with 7 (8.6%) controls (absolute % difference, 19.8% [95% CI, 8.2-31.4]). Retronasal olfactory function was also significantly worse in CRSsNP patients. Six months post-ESS, 30 patients (37.0%) experienced a clinically significant improvement in olfactory, whereas nonsignificant changes were observed in retronasal olfactory score, and 3.7% of patients experienced a deterioration of the olfactory function. In conclusion, although 37% of patients experienced a clinically significant improvement in their sense of smell following ESS, the overall prevalence of OD in this surgically naive population appears relatively low, especially when compared to that observed in patients with CRSwNP. Therefore, ESS may offer some benefits for enhancing orthonasal olfactory function, but the extent of these improvements appears to be limited.

Comparative analyses of post-infectious olfactory dysfunction between COVID-19 and non-COVID-19 cases

To identify the differences between COVID-19-associated and non-COVID-19-associated olfactory dysfunction (OD), we analyzed demographic and clinical characteristics based on the causative virus (COVID versus non-COVID groups) in patients with post-infectious olfactory dysfunction (PIOD) who underwent the olfactory questionnaire and olfactory function test. Out of 169 patients with PIOD, 99 were diagnosed with COVID-19 (COVID group), while 70 were not (non-COVID group). The COVID group was younger and had a higher percentage of male patients as well as patients with parosmia than the non-COVID group. In the initial olfactory function tests, the TDI, discrimination and identification scores were significantly higher in the COVID group than in the non-COVID group. TDI scores were significantly increased in patients with PIOD after treatment, regardless of the group. The threshold score was significantly increased by 1.38 in the COVID group while the identification score was significantly increased by 2.67 in the non-COVID group. Patients with COVID-19-associated OD were younger in age, tended to be male, had a higher incidence of parosmia, and had better initial olfactory function test results compared to those with non-COVID-19-associated OD. Following treatment, odor detection threshold improved in the COVID group, whereas odor identification improved in the non-COVID group.

Assessing determinants and trends in bird species identification skills among students: a comparative analysis with early 2000s data

ABSTRACT The decline of Earth’s biodiversity highlights the crucial role of knowledge about species in understanding ecological interdependencies and supporting conservation efforts. This study assessed bird species identification skills among 1752 students (46.4% boys, 51.9% girls, 1.1% diverse) in grades 4–12 from different school types, focusing on 30 species. Demographic and individual factors were examined for their impact on bird species identification. Comparative analyses with a 2005 dataset reveal a significant 37.75% decrease in students’ ability to correctly name birds at the species level. The average identification score was 6.84 (SD = 4.10) out of 30. Most students were only able to classify birds at the taxonomic level of family or order, but not at the species level. Factors such as age, school type, garden stay, distance to green space, interest in birds, perception of birds, and animal-related activities significantly influenced bird species identification. The study reveals a decline in bird species identification skills across all school types, particularly in schools of the highest stratification level, which nowadays have lower identification scores than medium stratification schools in 2005. The implications for educational institutions, particularly in the context of Education for Sustainable Development, emphasise the need for a reevaluatingcurriculum and teaching methods.

As a phenomenon: Ramadan fasting improves olfactory performance.

The present study objectived to investigate the influence of Ramadan fasting (RF) on olfactory function. Sixty-two participants were included in the current prospective study. The odor threshold and identification performances were determined by using the Connecticut Chemosensory Clinical Research Center (CCCRC) test initially (day 0) and on the first and last day (30th) of RF. Body weight (BW)s were measured initially and at the end of the study. The results were analyzed statistically. The average of baseline and last-day BWs were 78.38 ± 12.96 and 78.36 ± 12.39 kg, respectively. No significant difference was determined in terms of BWs (p = .932, p > .05). In the evaluation of CCCRC test outcomes, significant differences were observed in the scores of butanol thresholds (p = .0001), odor identification (p = .0001), food-related odors identification (p = .0001), and the number of normosmic individuals (p = .0001) at different times (p < .05). The thresholds scores (p = .0001, p = .0001), the identification scores (p = .0001, p = .0001), food-related odors identification scores (p = .0001, p = .0002), and the number of normomic individuals (p = .001, p = .001) detected on 30th day were significantly higher than on 0th and 1st days; respectively (p < .05). Additionally, the threshold scores (p = .0001), the identification scores (p = .003), food-related odors identification scores (p = .007), and the number of normosmic individuals (p = .018) detected on day 1 were significantly higher than on day 0 (p < .05). The current study demonstrated that Ramadan fasting enhances the olfactory detection threshold and odor identification scores, significantly improving the identification of food-related odors. The results may indicate that Ramadan fasting improves olfactory performance. Level II.

Parosmia in patients with post-infectious olfactory dysfunction in the era of COVID-19-associated olfactory impairment.

Alarge number of patients with olfactory impairment are affected by parosmia or phantosmia. This study aimed to examine the demographic and clinical characteristics of parosmia. We performed aretrospective data analysis of patients consulting at our Smell and Taste Outpatient Clinic. Atotal of 297 patients were included (203 women, mean age44.4 ± 13.7years). Olfactory function was quantified using the "Sniffin' Sticks" composite TDI (odor threshold, determination, and identification) score. The presence of qualitative olfactory impairment was assessed trough medical history and aparosmia questionnaire. Most of the patients showed olfactory impairment after an infection with SARS-CoV‑2 (84%) and were diagnosed with parosmia (49%). Patients with parosmia (PAR) (n = 201) were significantly younger compared to the group without parosmia (noPAR; n = 92) (PAR 43.2 ± 13years vs. noPAR 47 ± 15.1 years, p = 0.03) and had aslightly shorter duration of disease, without reaching statistical significance (PAR 10.3 ± 4.9months, noPAR 13.6 ± 37.6 months, p = 0.23). They also had higher TDI scores (PAR 24.3 ± 7points, noPAR 21.4 ± 8.2points, p = 0.003). Patients affected by parosmia were younger and had abetter olfactory function compared to patients without parosmia.

Utility of the modified Ottawa score for identification of more preferable candidates of extended anticoagulation therapy in cancer-associated isolated distal deep vein thrombosis: insight from the ONCO DVT Study

BackgroundThe ONCO DVT study (Edoxaban for 12 Months Versus 3 Months in Patients With Cancer With Isolated Distal Deep Vein Thrombosis) revealed superiority of 12-month relative to 3-month edoxaban treatment for the thrombotic risk in cancer-associated isolated distal deep vein thrombosis. However, it is unknown whether the superiority could be common in different modified Ottawa score subgroups. ObjectivesTo identify more preferable candidates for extended anticoagulation in patients with cancer-associated isolated distal deep vein thrombosis using the modified Ottawa score. MethodsIn this post-hoc subgroup analysis of the ONCO DVT study, we stratified 601 patients into the low (≤−1, N = 126), intermediate (0, N = 323), and high (≥1, N = 152) modified Ottawa score subgroups and compared clinical outcomes between the 12-month and 3-month edoxaban treatment groups. ResultsThe cumulative incidence of symptomatic recurrent venous thromboembolism or venous thromboembolism–related death was not different between the 12-month and 3-month edoxaban treatment groups in the low score subgroup (0.0% vs 2.2%), whereas it was lower in the 12-month than in the 3-month edoxaban treatment group in the intermediate (0.8% vs 7.6%) and high (3.1% vs 15.6%) score subgroups. There were no significant differences in the cumulative incidences of the major bleeding between the 12-month and 3-month edoxaban treatment groups in the low (10.1% vs 7.6%), intermediate (8.8% vs 5.0%), and high (13.9% vs 12.6%) score subgroups. ConclusionA 12-month compared with 3-month edoxaban treatment showed a lower risk of thrombotic events in patients with cancer-associated isolated distal deep vein thrombosis in the intermediate and high modified Ottawa score subgroups but not in the low score subgroup, suggesting a limited benefit of extended anticoagulation therapy beyond 3 months in patients with low modified Ottawa score.

Residual feature decomposition and multi-task learning-based variation-invariant face recognition

AbstractFacial identity is subject to two primary natural variations: time-dependent (TD) factors such as age, and time-independent (TID) factors including sex and race. This study aims to address a broader problem known as variation-invariant face recognition (VIFR) by exploring the question: “How can identity preservation be maximized in the presence of TD and TID variations?" While existing state-of-the-art (SOTA) methods focus on either age-invariant or race and sex-invariant FR, our approach introduces the first novel deep learning architecture utilizing multi-task learning to tackle VIFR, termed “multi-task learning-based variation-invariant face recognition (MTLVIFR)." We redefine FR by incorporating both TD and TID, decomposing faces into age (TD) and residual features (TID: sex, race, and identity). MTLVIFR outperforms existing methods by 2% in LFW and CALFW benchmarks, 1% in CALFW, and 5% in AgeDB (20 years of protocol) in terms of face verification score. Moreover, it achieves higher face identification scores compared to all SOTA methods. Open source code.

Optimizing CNN-LSTM for the Localization of False Data Injection Attacks in Power Systems

As the informatization of power systems advances, the secure operation of power systems faces various potential network attacks and threats. The false data injection attack (FDIA) is a common attack mode that can lead to abnormal system operations and serious economic losses by injecting abnormal data into terminal links or devices. The current research on FDIA primarily focuses on detecting its existence, but there is relatively little research on the localization of the attacks. To address this challenge, this study proposes a novel FDIA localization method (GA-CNN-LSTM) that combines convolutional neural networks (CNNs), long short-term memory (LSTM), and a genetic algorithm (GA) and can accurately locate the attacked bus or line. This method utilizes a CNN to extract local features and combines LSTM with time series information to extract global features. It integrates a CNN and LSTM to deeply explore complex patterns and dynamic changes in the data, effectively extract FDIA features in the data, and optimize the hyperparameters of the neural network using the GA to ensure an optimal performance of the model. Simulation experiments were conducted on the IEEE 14-bus and 118-bus test systems. The results indicate that the GA-CNN-LSTM method achieved F1 scores for location identification of 99.71% and 99.10%, respectively, demonstrating superior localization performance compared to other methods.

AROMHA Brain Health Test: A Remote Olfactory Assessment as a Screen for Cognitive Impairment.

Cost-effective, noninvasive screening methods for preclinical Alzheimer's disease (AD) and other neurocognitive disorders remain an unmet need. The olfactory neural circuits develop AD pathological changes prior to symptom onset. To probe these vulnerable circuits, we developed the digital remote AROMHA Brain Health Test (ABHT), an at-home odor identification, discrimination, memory, and intensity assessment. The ABHT was self-administered among cognitively normal (CN) English and Spanish speakers (n=127), participants with subjective cognitive complaints (SCC; n=34), and mild cognitive impairment (MCI; n=19). Self-administered tests took place remotely at home under unobserved (among interested CN participants) and observed modalities (CN, SCC, and MCI), as well as in-person with a research assistant present (CN, SCC, and MCI). Olfactory performance was similar across observed and unobserved remote self-administration and between English and Spanish speakers. Odor memory, identification, and discrimination scores decreased with age, and olfactory identification and discrimination were lower in the MCI group compared to CN and SCC groups, independent of age, sex, and education. The ABHT revealed age-related olfactory decline, and discriminated CN older adults from those with cognitive impairment. Replication of our results in other populations would support the use of the ABHT to identify and monitor individuals at risk for developing dementia.

Short-term efficacy of platelet-rich plasma in the treatment of persistent olfactory dysfunction: systematic review and meta-analysis.

To assess the short-term effects of topical platelet-rich plasma (PRP) injection on persistent refractory olfactory dysfunction. A comprehensive literature search of the PubMed, SCOPUS, EMBASE, Web of Science, Google Scholar, and Cochrane databases was conducted for articles up to November 2023. The search focused on studies that compared the amelioration of olfactory dysfunction between a topical PRP treatment cohort and a control group (receiving either placebo or no treatment), along with pre- and post-treatment comparisons. Subgroup analysis of the evaluation of olfactory function was also performed. The improvement in olfactory scores 1-3months post-treatment (standardized mean difference = 1.5354 [95% confidence interval: 0.7992; 2.2716], I2 = 83.8%) was greater in the treatment group than in the control group. In the treatment group, PRP increased the threshold, discrimination, and identification (TDI) score for Sniffin' Sticks by > 5.5 (minimum clinically significant difference; mean difference = 6.1789 [3.9788; 8.3789], I2 = 0.0%), indicating clinically significant improvement based on verified examinations. The rate of significant improvement among patients was 0.6683 [0.5833; 0.7436] after treatment. All TDI subdomains were significantly and similarly improved after treatment. This meta-analysis suggests that injection of PRP into the olfactory fissure or surrounding mucosal areas is an effective treatment for persistent refractory olfactory dysfunction in the short term.

Executive functions in mid-life adults with mild sensorineural hearing loss compared with age-matched controls with normal hearing

PurposeThis study explores the relationship between sensorineural hearing loss (SNHL) in mid-life adults and cognitive function, focusing on executive functions. Given the projected rise in dementia cases, identifying modifiable risk factors for cognitive decline is imperative. SNHL has emerged as a potential risk factor, with hearing loss accounting for a substantial portion of dementia cases. However, the cognitive implications of SNHL in mid-life adults are not well understood.MethodThe study examined 50 participants, 25 with bilateral unaided mild SNHL (AHL) and 25 with normal hearing (ANH). A battery of audiological assessments and cognitive tests, including the Trail Making Test (TMT), was administered. TMT measures included direct scores (completion time and errors) and derived scores (difference, ratio, proportion, sum, and multiplication scores).ResultsThe AHL group displayed significantly poorer peripheral hearing compared to the ANH group, as reflected in pure-tone audiometry, speech reception thresholds, and speech identification scores. Significant differences were observed in all direct and derived TMT measures except for the ratio and proportion scores. This suggests that while overall cognitive disturbances were evident in the AHL group, they were not exclusive to executive function deficits. Notably, we did not identify any statistically significant effects of hypertension, diabetes, smoking, alcohol consumption, or physical activity on TMT scores.ConclusionThis study highlights the potential impact of SNHL on cognitive function in mid-life adults. Mid-life SNHL is associated with cognitive differences, emphasizing its role as a modifiable risk factor for future cognitive decline. This research underlines the need for further investigation into the cognitive effects of aided hearing and a multidisciplinary approach to understanding these alterations in cognitive function.

Test-retest reliability and normative data for “Seven-iTT”, a test for the assessment of taste and oral trigeminal function

BackgroundAssessment of taste and somatosensory perception in clinical practice lacks fast tests that are validated and reliable. Recently, a 12-item identification test for taste and oral trigeminal perception, and its shorter version, the Seven-iTT, was developed. The objectives of this study were to evaluate its test-retest reliability and establish normative data. New methodTwo-hundred participants (120 women, 80 men) with a good sense of taste performed a whole-mouth identification test using 12 filter-paper strips impregnated with low and high concentrations of sweet, sour, salty, bitter, astringency, and spiciness. Fifty of them repeated the task, with a median interval of 122 days from the first visit. Test-retest reliability was determined using Spearman correlation and the Bland–Altman plot method. ResultsThere was a significant correlation in identification score between the first and the second session for both versions of the test (r ≥ 0.28; p ≤ 0.048). The Bland–Altman plot reflected a good congruence between the results of the two sessions. Additionally, frequencies of correct identification were consistent between sessions, with women outperforming men (p = 0.005). Hypogeusia was established at Seven-iTT score of 3 of less. Comparison with existing methodsThe identification test combines taste and somatosensory perception, thus creating a more detailed diagnosis tool. Scores were correlated with self-rated taste perception. ConclusionThe present results confirmed the applicability of Seven-iTT for a reliable, fast evaluation of taste and somatosensory perception in the general population, that can be extended to clinical practice.

The effect of smell training on COVID-19 induced smell loss.

while smell training appears to be effective for post viral smell loss, its effectiveness in COVID-19 induced smell loss is currently not well known. Therefore, we aim to investigate the potential effect of smell training on patients with COVID-19 induced smell loss. we conducted a case-control study with two comparable cohorts. One of which (n=111) was instructed to perform smell training twice daily for 12 weeks, therapeutical adherence was monitored on a daily schedule, while the other cohort (n=50) did not perform smell training. The Sniffin' Sticks Test (SST) was used to objectify participants' sense of smell at baseline and after 12 weeks, reported as a Threshold, Discrimination, and Identification (TDI) score. We also determined the association between therapeutical adherence and the TDI scores. we found a significant difference in psychophysical smell function between patients with COVID-19 induced smell disorders who performed 12 weeks of smell training and those who did not. Median TDI difference between groups was 2.00 However, there was no association between the therapeutical adherence and olfactory function. we discovered a significant moderate difference in psychophysical smell function between patients with COVID-19-induced smell disorders who performed smell training and those who did not, implying a possible advantage of training. However, no relationship was found between therapeutical adherence of smell training and olfactory function.

Retuning Ears &amp; Rewiring Brains for Effective Communication: Foreign-Accent Perception &amp; Sensitivity Training (FAPST)™

Purpose: Communication and psychosocial challenges are associated with processing regional or foreign accents. These challenges result in discrimination, marginalization, and reduced opportunities for culturally, linguistically, or racially diverse people. As a departure from the controversial approaches of training speakers to speak more effectively, this paper presents an innovative and effective methodology to train listeners instead and make the communication environment more “accent friendly”. Built upon two decades of testing and evidence, the Foreign Accent Perception &amp; Sensitivity Training (FAPST)TM is used to develop skills in listening to accents, reducing implicit biases, and increasing appreciation and enjoyment for interacting with accents and cultures. Methodology: 320 undergraduate students from eight sections of a Diversity Issues course were provided the FAPST training online that included 15-20 minutes of gamified experience, over four weeks, in listening and identifying 54 varieties of accent in a structured, multimedia procedure. Assessments included weekly Accent Identification Scores as well as a pre- and post-survey using the CCQ tool to assess listeners’ baseline knowledge, attitudes, stereotypes, preferences, and skills related to processing accents. They also received formative assessments, feedback, and engaged in self-reflections. Results: Paired t-tests showed significant improvement in Accent Identification Scores which increased from 52% in week 1 and reached 75% by week 4, significant at p &lt;0.05 level. The post-training CCQ survey results showed that Factual Knowledge scores improved significantly from 42% to 78%, Stereotypes scores reduced significantly from 89% to 22%, and Competence scores improved significantly from 23% to 76%. Participants reported increased confidence in listening accuracy and improvement in noticing details in accent patterns. Participants reported increased interest and willingness to interact with diversity. Participants also reported increased awareness of discrimination, and willingness to show allyship and advocacy for diverse individuals. Conclusion: This project confirmed that students have preconceived attitudes and biases as well as lower skills and confidence in interacting with diversity and accents which factor in their decisions and preferences to communicate with people with certain accents. It becomes imperative to set students up for success and engagement in a globalized world by training them with skills to navigate diversity. Results show that such a training improves listening accuracy as well as develops increased confidence and interest in engaging with diversity, while reducing implicit biases and stereotypes, along with increased factual knowledge of, and competence with accents.

Effectiveness of initiating advance care planning among older outpatients through intervention by physicians trained in a model discussion video: A randomized controlled trial.

This study aimed to assess the impact of a physician-led intervention on advance care planning (ACP) introduction among older outpatients using a model discussion video. This prospective interventional study included Japanese general practice outpatients aged ≥65 years. All participants received an ACP leaflet. Co-researchers were trained using a model discussion video based on the "Serious Illness Conversation Guide," and provided ACP introduction explanations to the intervention group to ensure intervention content consistency. The control group received the ACP leaflet only, with no standardized explanations. The primary outcome was ACP discussion occurrence. Secondary outcomes included ACP engagement (assessed through the 4-item ACP Engagement Survey), engagement score for advance directives acquisition and score for surrogate decision-maker identification, and anxiety incidence (assessed through Generalized Anxiety Disorder-7). This study included 48 participants: 25 (52.1%) in the intervention group and 23 (47.9%) in the control group. Regarding primary outcome, the intervention group had significantly more ACP discussions compared with the control group (92.0% vs 26.1%, adjusted odds ratio 50.2, P = 0.0012). Regarding secondary outcomes, the intervention group showed greater readiness (mean scores for the 4-item Engagement Survey [P = 0.0001], engagement score for advance directives acquisition [P = 0.01] and score for surrogate decision-maker determination [P = 0.03]) than the control group, without increasing anxiety. This physician-led ACP introduction for older patients in a Japanese general practice setting enhanced ACP readiness and stimulated discussions, without increasing anxiety. The model discussion video for ACP introduction might effectively train physicians in general practice settings. Geriatr Gerontol Int 2024; ••: ••-••.
